On This Day, July 17: Earliest Recorded Solar Eclipse

Posted on by Dan

The Sun stood in constant awe and reverence in the ancient world. Nobody knew exactly what it was, but people knew it provided warmth and life to the living world. Because of this, people tracked the path of the Sun and often worshipped it as a god. So, imagine the reaction that would occur when the Sun vanished in the middle of the day.

On July 17, 709 BCE, court astronomers in in Qufu, capital of the ancient Chinese state of Lu, watched and recorded this exact event. It was recorded in the Spring and Autumn Annals (Chunqiu), with the line “the Sun was totally eclipsed”, marking the first recoding in human history of a solar eclipse. Without modern astronomy, ancient civilizations could not explain what they were witnessing. Across the world, eclipses were often interpreted as supernatural omens – warnings from the gods, signs of political upheaval, and so on. Recording these events must have seemed like a good idea.

Over centuries, Chinese, Babylonian, Greek, and later Islamic astronomers accumulated additional observations of eclipses. They began to notice that they were not random but occurred in predictable patterns. Today, astronomers can predict a solar eclipse centuries in advance with extraordinary precision. Using our understanding of gravity and orbital mechanics, we know exactly when the Moon’s shadow will cross Earth’s surface and where totality will occur down to the second.

On This Day, July 16: Trinity Test

Posted on by Dan

For thousands of years, humanity sought to understand the fundamental building blocks of matter. What began decades earlier as a quest to understand the nature of the atom culminated in one of the most consequential moments in history. On the morning of July 16, 1945, a brilliant flash illuminated the New Mexico desert as the Trinity Test became the first successful detonation of a nuclear weapon, ushering in the Atomic Age.

As with many new technologies, the path to a nuclear weapon began much earlier with discoveries that transformed our understanding of the atom. Scientists such as Henri Becquerel, Marie Currie, Ernest Rutherford, Niels Bohr, and many others gradually revealed that the atom was in fact not indivisible but consisted of other elementary particles. These particles are arranged in a complex structure that stores an enormous amount of energy, some of which can be released under the right conditions. 

Fearing that Nazi Germany would develop an atomic bomb first, the United States launched the Manhattan Project to develop its own atomic bomb. The Manhattan Project brought together many of the world’s leading scientists and engineers, and after a few years of intense secrecy, research, and construction, it culminated in the Trinity Test.

The explosion exceeded expectations. The mushroom could rose to 7 miles high in the sky, with temperatures from the blast exceeding the surface of the Sun. Although the Trinity Test marked the birth of the nuclear age, it also demonstrated the remarkable power of scientific inquiry. Some of the same discoveries that led to nuclear weapons also gave rise to nuclear energy, advanced imaging technologies, carbon dating, and a deeper, more complete understanding of the universe itself.

On This Day, July 15: Rosetta Stone Discovered

Posted on by Dan

The hieroglyphics covering ancient Egyptian monuments spoke a language that nobody could understand. That changed on July 15, 1799, when a fortuitous discovery gave scholars the key they had been searching for. While strengthening the defenses of Fort Julien near the town of Rosetta, French soldiers serving in Napoleon’s Egyptian campaign uncovered a carved stone that initially looked ordinary enough. Yet that artifact, a large black basalt slab called the Rosetta Stone, became they key to deciphering the lost language of Egyptian hieroglyphics.

The Rosetta Stone contained on it a decree written in three different languages: Greek, Demotic, and Egyptian Hieroglyphics. Since the Greek language was known and could be read, researchers suspected the stone might serve as a translation key for the mysterious hieroglyphs. For nearly 1,500 years, no one could read the language of the ancient Egyptians. Their temples, monuments, and tombs were covered with elaborate symbols, but their meaning had been lost after the decline of the ancient Egyptian civilization. Some people even believed hieroglyphs were merely symbolic or mystical images rather than a true written language.

The breakthrough came in 1822 when French scholar Jean-Francois Champollion demonstrated that hieroglyphs represented both sounds and ideas, eventually unlocking the principles of the ancient writing system. Few archaeological discoveries have had such a profound impact. For the first time ever, historians could read the words carved onto Egypt’s temples, obelisks, and royal tombs, opening a window into more than three millennia of human civilization.

On This Day, July 14: Mariner 4 Mars Flyby

Posted on by Dan

Few worlds have captured the human imagination like Mars. For thousands of years, it was little more than a red dot in the night sky. Even after the invention of the telescope, people wondered and debated what the Martian surface was like, and many wondered if life had existed on the planet. On July 14, 1965, a small 575-pound spaceship called Mariner 4 made the first successful flyby of Mars, revealing close up photos of the planet’s surface.

Mariner 4 traveled more than 325 million miles over eight months to reach Mars, eventually passing within about 6,100 miles of the planet. For decades, some people, including a few scientists, believed Mars might harbor vegetation or remnants of advanced civilizations. The 22 photos from Mariner 4 replaced that speculation with evidence.

The photographs revealed a heavily cratered landscape that more closely resembled the moon instead of a living world. While this was disappointing for those who had hoped to find signs of life, it was a triumph for science. For the first time, humans had explored the surface of another planet not through imagination or speculation, but through direct observation. It also showed that interplanetary exploration was possible, paving the way for future missions such as Mariner 9, the Viking landers, and Mars rovers.

On This Day, July 13, Passing of August Kekule

Posted on by Dan

During the mid-1800s, chemists knew the atomic composition of many organic compounds but struggled to understand their arrangement. Carbon in particular was present in an astonishing variety of substances but nobody could explain why. August Kukele, who passed away on July 13, 1896, helped solve this problem by proposing that carbons atoms could bond to one another to form long chains. This idea became a cornerstone of organic chemistry, leading to the rapid growth in knowledge in organic chemistry in the following century.

Kukele’s most famous contribution to organic chemistry came in 1865, when he proposed the molecule benzene consisted of six carbon atoms linked together in a ring. The nature of his discovery also contains one of the most famous anecdotes in the history of science. Kukele claimed, nearly 25 years after proposing the structure of benzene, that the idea came to him after a dream where a snake seized its own tail. He awoke with a revelation: what if the carbon atoms in benzene from a closed ring rather than an open chain?

Kekule’s work underpins much of today’s modern organic chemistry. His vision (or dream?) of carbon atoms linked into rings provided chemists with an entirely new framework for understanding the molecular world. Our plastics, medicines, agricultural chemicals, synthetic fibers and various other industrial materials all rely on principles that trace back to his insights.

On this Day, July 12: First JWST Images

Posted on by Dan

The James Webb Space Telescope, NASA’s successor to the Hubble Space Telescope and the world’s most powerful telescope, was launched on Christmas Day of 2021. For months, astronomers knew the telescope was working, but nobody outside a small group of scientists had seen what it was capable of. On July 12, 2022, the first full-color images from the James Webb Space Telescope were finally released by NASA, to the delight of millions of people worldwide.

The images revealed stunning views of the Carina Nebula, the Southern Ring Nebula surrounding a dying star, Stephans Quintet of interacting galaxies, and the atmosphere of the exoplanet WASP-96b. The JWST observes the universe in infrared light, allowing it to penetrate clouds of cosmic dust, revealing parts of the universe that were previously invisible. Its primary mirror allows for more than six times the light collecting area than the Hubble telescope.

The JWST has to ability to transform our understanding of nearly every area of astronomy. It is currently being used to learn more about the formation of early galaxies and black holes, the birth of stars and planetary systems, and the atmospheres of distant worlds that may one day reveal life on another planet.

The Gap Between Jesus and the Gospels

Posted on by Dan

The belief among many Christians is that the Gospels of the New Testament provide an accurate account of the life, ministry, and death of Jesus. But the dating of the actual writings of the four Gospels throws this idea into serious doubt.  The truth is the Gospels were written decades after the death of Jesus that contain historical elements embedded with mythical stories of his life.

Matthew, Mark, Luke, and John
Matthew, Mark, Luke, and John

The Gospel According to Mark

The Gospel of Mark is the earliest written Gospel, and the best estimate is it was written around 70 CE. There are several lines of evidence to suggest this date. To begin with, it contains knowledge of the destruction of the Temple in Jerusalem, which occurred in the summer of 70 CE. The Gospel of Mark represents an early church leadership structure with an under-developed theology compared to that found later Gospel writings. Jesus is primarily depicted as an apocalyptic prophet and a suffering Messiah rather than the fully divine Son of God who is one with the Father.

We also know it was written before Luke and Matthew because each copies a significant amount of their Gospel from Mark. Matthew reproduces roughly 90% of Mark’s verses, while Luke preserves about two-thirds of them. In many cases, the wording is virtually identical. If the three Gospels represented completely independent eyewitness accounts, we would expect them to describe many of the same events but in their own unique language. Instead, entire paragraphs appear nearly word for word. The simplest conclusion is that both authors had a copy of Mark before them and used it as one of their primary written sources. Based on the above evidence, the Gospel of Mark fits in nicely as the earliest written Gospel with a date of about 70 CE – a full 40 years after Jesus’s death.

The Gospel According to Matthew

It’s fairly simple to provide a hard upper and lower limit when dating the Gospel of Matthew. We know it is written after Mark, providing a lower limit of around 70 CE. Ignatius of Antioch seems to be familiar with this Gospel, providing an upper dating limit of around 100-110 CE. The consensus of modern scholars is around 80-90 CE. This places it as written roughly 50 to 60 years after Jesus’s death.

As with the Gospel of Mark, the Gospel of Matthew contains knowledge of the destruction of the Temple in Jerusalem. It represents a more advanced church structure and theology than the Gospel of Mark, adding emphasis on Jesus as a divine authority. Mark was also used as a primary source when writing Matthew.  Approximately 90% of Mark’s verses appear here, many times word for word. The only way to have large sections in word for word agreement is if it was copied. 

The Gospel According to Luke

The Gospel of Luke was written about the same time as the Gospel of Matthew. The lines of evidence used to date it are also similar to Matthew. It contains knowledge of the destruction of the Temple of Jerusalem, it uses Mark as a primary source, and it contains a similarly advanced church structure and theology. Luke also begins by acknowledging that “many have undertaken to compile an account” before him. Rather than claiming to be an eyewitness, the author describes gathering traditions and written sources into an orderly narrative.

The Gospel of Luke is universally acknowledged as written by the same author as the Acts of the Apostles. The Acts describes the rapid expansion of Christianity through the Roman Empire, leading to the conclusion that the two-volume work was composed around 80-90 CE.

The Gospel According to John

The Gospel of John was the latest Gospel to be included in the New Testament, written around 90-100 CE. John’s Gospel is markedly different from the previous three. It includes a far more developed theology, suggesting decades of theological reflection within the early Christian movement. Jesus openly declares his divine identity, a theme that was completely absent in the earliest Gospel of Mark. John also refers to Judaism as “the Jews”, reflecting a sharp distinction between the Jewish and Christian communities. During Jesus’s life and shortly after his death, this distinction did not exist as Jesus and his followers were considered a sect of Judaism. 

The Gospel also presents a highly developed understanding of Jesus as the eternal Logos (“Word”) who existed before creation. This philosophical language shows the influence of decades of theological development and interaction with the wider Greco-Roman world.

Conclusion

Taken together, the four Gospels show a clear historical progression. Mark is the earliest and simplest account. Matthew and Luke build upon Mark while expanding both the narrative and the organization of the early church. John represents an even later stage, presenting a far more developed theology and a Christian community that had become increasingly distinct from Judaism.

The chronological gap between Jesus’s death and the writing of the Gospels is significant. Mark was written roughly forty years later, Matthew and Luke about fifty to sixty years later, and John perhaps sixty to seventy years after the events it describes. During those decades, stories about Jesus circulated primarily through oral tradition before eventually being written down by anonymous authors.

None of this necessarily means that the Gospels contain no authentic historical memories. Ancient traditions often preserve elements of genuine events. However, it also does mean they should not be approached as contemporaneous eyewitness reports. Instead, they are theological narratives produced by later Christian communities for a Christian audience that sought to explain who Jesus was and what his life meant. Understanding when the Gospels were written is therefore essential for distinguishing between the historical Jesus and the beliefs that developed about him over the course of the first century.

Who Wrote the Gospels?

Posted on by Dan

The Christian Gospels are considered by Christians to be the Word of God; however, this idea breaks down spectacularly once anyone investigates deeply about who wrote them. A lot of Christians believe that the Gospels were written by the authors Matthew, Mark, Luke, and John. But the truth is there were all anonymously written, and it’s uncertain that any were written by the four authors adscripted to them. Let’s see why this is the case.

Matthew, Mark, Luke, and John
Matthew, Mark, Luke, and John

The Gospel According to Mark

The Gospel of Mark is the earliest written Gospel, and is attributed to John Mark, a disciple of the Apostle Peter.  The Gospel according to Mark, as with all four Gospels, are written in competent Greek prose by highly educated authors. This powerful theme covering all four Gospel authors strongly suggests they were not written by their traditional attributions. The Apostles and disciples of Jesus spoke Aramaic, were from the lower class, and like all lower-class peasants of the time were most likely illiterate.  While it is possible that Peter was associated with a highly literate Greek, it is highly uncertain and there are better reasons to doubt the claim than to believe it.

Additionally, the Gospel never claims to be written by Mark, never claims to be an eye-witness account, and is written in the third person that reads more like a collection of oral traditions rather than a memoir.  

Could the Gospel of Mark been written by Mark?  It’s possible but we have no way of knowing for sure one way or another.

The Gospel According to Luke

The Gospel of Luke is attributed to Luke, a traveling companion of Paul.  It is the most likely to be written by the author attributed to it, however by saying it is the most likely is not the same as saying that it is likely. As with the other four gospels it’s still anonymous, does not claim to be an eye-witness account, and was written in highly educated Greek prose.  It uses earlier sources such as the Gospel of Mark, many passages which were copied word for word. 

There is a striking curiosity with the Gospel of Luke. Paul’s letters contain very little portrayal of Jesus’s life.  Lukes Gospel is the opposite.  If they were both close companions, why such the stark difference in Information?  One should expect a lot of overlap from two people working closely together. 

The Gospel According to Matthew

The Gospel of Matthew is attributed to the Apostle Matthew, a former tax collector called upon to be a disciple of Jesus. This Gospel is certainly not written by Matthew. Around 90% of Matthew is copied from Mark, many times word for word. Why would Matthew, an eyewitness to the life of Jesus, copy word for word the account of Mark, who was not an eyewitness? Why not rely on your own memories and experiences?

It is also noteworthy that this Gospel refers to Matthew in the third-person. 

“Jesus saw a man called Matthew sitting at the tax booth” – Matthew 9:9

This Gospel reflects an older church structure, which is why scholars date its writing around 80-90 CE.  If Matthew was in his 20s or 30s during Christs ministry that would put his age around 80 of the writing.  Again, this is not entirely impossible, but unlikely. 

Applying Occum’s Razor, it requires a remarkable series of special explanations to believe that Matthew was the author of this Gospel.  Someone throughout the course of his life he would have had to learn Greek prose, a rarity for the lower class in the ancient world.  He would have had to live well into his 80s while maintaining sufficient cognition to write elegant Greek prose, while referring to himself in the third person. Yet this begs the questions, why did he have to rely word for word on a non-eyewitness account for much of his Gospel?

The Gospel According to John

The Gospel of John is attributed to the Apostle John. The Gospel of John is the latest written Gospel, likely around 90-100 CE.  This alone would put John at such an advanced age as to disqualify him as the author.  Could he have written this Gospel at 90 to 100 years of age?  Not impossible.  Could I hit the Powerball 5 times in a row?  This is also not a mathematical impossibility, but it’s also not the same thing as saying it’s probable.

The Acts of the Apostles describes John as “unlettered” meaning illiterate.  The Gospel of John is written in sophisticated Greek prose.  This is a glaring mismatch that would require us to assume, in the absence of evidence or good precedent, that John received a strong Greek education over the course of his adult life.

The Gospel also appears to have been written by a community, as it states, “we know that his testimony is true”. Who is “we”? It is the Johannine community that endorses this writing. The Gospel itself contains passages awkwardly connected and seems to have undergone multiple revisions.

The Anonymous Gospels

In the end, the traditional claim that Matthew, Mark, Luke, and John personally authored the four Gospels rests more on church tradition than on historical evidence. The texts themselves are anonymous, written decades after Jesus’s death, composed in educated Greek, and often rely on earlier written sources rather than firsthand testimony. While it is impossible to rule out the traditional attributions with absolute certainty, the evidence points in a different direction. The most reasonable conclusion is that the Gospels emerged from early Christian communities, preserving beliefs and traditions about Jesus rather than serving as direct eyewitness memoirs from the men whose names they later received.

1929: Hubble’s Law

Posted on by Dan

In the late 1920s, the conceptual seeds of what would become the Big Bang theory were just beginning to emerge. At this time many scientists supported the Steady-State model. The discovery of Hubble’s Law by the American astronomer Edwin Hubble in 1929 added a significant piece of observational data in support of the expansion of the universe, a critical feature of the Big Bang Theory’s model. Hubble’s Law is the observation that galaxies are moving away from the Earth at speeds proportional to their distance away from the Earth. The further away a galaxy is from the Earth, the faster it is moving away.

The Cosmic Backdrop Before 1929

The early 20th century was a time of astronomical upheaval. For centuries, astronomers believed that the Milky Way galaxy was the entire universe. But in the early 1920s Edwin Hubble showed that this was not the case. Using the 100-inch Hooker Telescope at Mount Wilson Observatory in California, he identified Cepheid variable stars in the Andromeda Nebula. Using these stars as distant markers, he calculated their distance to be 900,000 light years away (later revised upwards to 2.5 million), and he was able to show the Andromeda was a separate galaxy. This realization increased the size of the universe from a single galaxy up to billions of galaxies. The known universe was now vastly larger.

Meanwhile, another astronomer, Vesto Slipher, had been measuring the spectra of spiral nebulae since 1912. He noticed that most of these nebulae showed a “redshift”, meaning their lights stretched toward the red end of the spectrum indicating that they were moving away from us. Since at the time nebulae were not thought to be other galaxies, Slipher did not realize the significance of his observations. By 1925, Slipher had measured redshifts for 42 galaxies, with velocities up to 1,800 kilometers per second.

Piecing the Puzzle Together: Velocities, Redshifts, and Distances

Hubble combined Slipher’s velocity data with his distance data and in 1929 he published his findings in the Proceedings of the National Academy of Sciences. Hubble discovered a rough but undeniable linear relationship between a galaxy’s redshift velocity and distance from Earth that could easily be plotted on a graph. The relationship can be written as v = H₀ d, with v as recession velocity, d as distance, and H₀ as the Hubble constant – a measurement of how quickly space is stretching.

Hubble’s law is sometimes referred to as the Hubble-Lemaitre Law because of the work of a Belgian priest and astronomer, George Lemaitre. In 1927, Lemaitre independently worked out Hubble’s law, arguing that the field equations from Albert Einstein’s General Theory of Relativity showed the universe is not static. To keep the universe static, Einstein added a coefficient he called the cosmological constant. Lemaitre went further, and he took some of the available redshift measurements, combined them with the available distant measurements, and noticed a linear trend between the two. However, his work was published in a little read French journal, so its impact was minimal, and Lemaitre opted to cite Hubble’s better and stronger data in giving credit to Hubble for the discovery of the law. After Hubble’s publication, Einstein abandoned his concept of a cosmological constant, calling it the “biggest blunder” of his career, although it’s been revived in recent decades to account for dark energy.

The implications of Hubble’s law are important. If galaxies are all expanding from each other, then rewinding time suggests they all more crammed together. Rewind time far enough, back to the beginning of the universe, and you arrive at a dense, hot beginning – the Big Bang.

Initial Skepticism and Hubble’s Legacy

Hubble’s original value for his constant implied a universe younger than the Earth, puzzling scientists and shedding doubt on his results. Better telescopes, resulting in improved distance measurements, resolved this in the coming decades. Modern estimates place the Hubble constant near 70 km/s/Mpc, yielding an age of 13.8 billion years. The Hubble Space Telescope, launched by NASA in 1990 and named in his honor, has carried Hubble’s discovery into orbit, using Hubble’s law to map the expansion of the universe across billions of light-years.

Hubble’s 1929 breakthrough stands as one of astronomy’s greatest triumphs. Within a few years it elevated Georges Lamaitre’s previously ignored 1927 “Big Bang” theory from mathematical curiosity to mainstream cosmology. In the process it transformed our picture of reality from a static, island universe to the vast, to the expanding cosmos from a beginning that we know of today. Nearly a century later, Hubble’s Law remains the central pillar of observational cosmology.

Science as a Force for Progress Part 10: Frontiers Ahead

Posted on by Dan

In the previous part of this series, we explored how Turing, Berners-Lee, and advances in computing and neuroscience created a digital ecosystem that connects minds and accelerates knowledge like never before. In this final part, we reflect on science’s triumphant arc – from centuries dominated by superstition and untestable beliefs to an era of evidence-based mastery over nature’s deepest challenges. Where once plagues were divine wrath and comets omens of doom, today vaccines eradicate diseases and telescopes reveal cosmic truths. As we enter 2026, breakthroughs in quantum computing, biotechnology, fusion energy, space exploration, and artificial intelligence exemplify this shift: replacing fear with understanding, prayer with precision, and limitation with limitless potential. These advances promise to conquer illness, secure sustainable power, unveil the universe, and amplify human intellect – yet they remind us that science’s true power lies in its rigorous, self-correcting pursuit of evidence.

From Superstition’s Shadow to Evidence’s Light

For millennia, humanity attributed misfortune to supernatural forces: earthquakes as godly anger, illnesses as curses, celestial events as portents. Prayers and rituals offered solace but no solutions, leaving life precarious and short. Science overturned this worldview through observation, experimentation, and reproducibility – transforming mystery into mechanism.

Today, this contrast is stark. Where medieval societies blamed miasmas or sin for epidemics, modern microbiology and vaccines, rooted in Pasteur’s germ theory, have nearly eliminated smallpox and dramatically curbed measles. Ancient astrologers read fates in stars; now, telescopes like James Webb pierce cosmic dawn, revealing early galaxies, potential biosignatures on exoplanets, and even a new moon around Uranus in 2025 observations.

In health, superstition once prescribed bloodletting or charms; evidence now delivers CRISPR therapies. 2025 saw one-time infusions safely slashing cholesterol by over 50% in high-risk patients via gene editing targeting ANGPTL3, while trials advanced cures for sickle cell, amyloidosis, and rare disorders – building on Watson, Crick, and Franklin’s DNA helix. These are not miracles, but measurable outcomes of methodical inquiry.

A New Era of Discovery

Quantum computing exemplifies progress over prophecy. IBM’s 2025 Nighthawk processor and advancements toward fault-tolerant systems by 2026–2029 promise simulations of molecules for drug design and materials unattainable classically, echoing Curie’s atomic revelations but harnessing them for practical quantum advantage.

Nuclear fusion, long dismissed as eternally distant, advanced decisively: China’s EAST tokamak accessed a “density-free regime” in late 2025, sustaining high-density plasmas for ignition pathways, while global efforts like WEST’s record plasma durations and high-temperature superconductors push toward commercial viability in the 2030s – offering clean, abundant energy without fossil fuels.

Space discoveries further illuminate: Webb’s 2025 views captured supernovae from the universe’s infancy and carbon-rich exoplanet atmospheres hinting at habitability, extending Hubble and Gamow’s Big Bang insights.

Artificial intelligence accelerates it all. 2025 models excelled on reasoning benchmarks, aiding fusion control, protein design, and hypothesis generation – propelling us toward systems that augment discovery, far from oracles but grounded in data.

From Copernicus repositioning Earth to these revolutions, science has liberated humanity from superstition’s grip, delivering longer lives, interconnected knowledge, and tools to address existential threats. The future gleams with promise: eradicated diseases, limitless clean energy, interstellar exploration, and intelligence beyond biological limits. Yet ethical stewardship—ensuring equitable access, safe AI, and responsible gene-editing demands the same evidence-based rigor.

This series has chronicled science not as arcane facts, but as humanity’s greatest force: dismantling myths, illuminating truths, and empowering progress. Its method – question, test, refine – holds no bounds when guided by curiosity and accountability. In an age where evidence triumphs over enchantment, science lights the way ahead.

Thank you for joining this journey through Science as a Force for Progress.
