The Discovery of Pulsar Stars

Leave a comment

Neutron stars were thought to be preposterous when first suggested until 1967 when scientists used radio-antenna telescopes to map the universe. 3 pulses would be unusual, 4 pulses would be phenomenal, but scientists had received pulses from certain parts of the universe 24 hours per day, 7 days per week for months on end. The reason the pulses occurred was because every rotation of the neutron star causes energy to swipe past Earth exactly how light from a lighthouse sweeps light onto the oceans. Scientists first thought the pulses were from aliens until they proposed that the new star had to be denser than any type previously discovered, being the size of a planet but with the power of a star. Astronomers named these new stars “pulsars” and investigated continuously until 1 year later when they found a pulsar, burried deep within the remains of a super local, the pulsar known as the “Crab Pulsar” which is the closest pulsar to Earth. Interestingly, Swiss astronomer Fritz Zwicky had mathematically proven this phenomena 80 years prior but was labeled a hack for his wild theories

The Advent and Evolution of Noodles Within China

Leave a comment

The oldest known noodles ever discovered were found in China and date back 4000 years, discovered virtually fully preserved in a sealed bowl buried beneath sediment. These noodles were not made of wheat but rather from millet, which provides insight into early culinary traditions of the ancient world. These millet based noodles were distinct from future varieties which relied upon wheat, reflecting the grains available in ancient China during the period. This discovery demonstrates the early noodle making techniques which became refined over the coming centuries. By 400 B.C., noodles existed across Asia, likely produced by mixing flour and water into a dough. In comparison to the noodles from 400 B.C., which were likely produced using wheat or other grains and kneaded into dough, the 4000 year old noodles appeared to have been hand pulled and stretched into thin strands rather than being cut. By 400 B.C., more structured noodle cutting methods had emerged, allowing for different regional styles and preparations of noodles to develop (e.g. Lamian which is a hand pulled noodle still popular during the modern day, Dao Xiao Mian which is shaved directly from a block of dough, Biang Biang Mian which is known for its wide belt like shape etc.). These discoveries highlight not only the ingenuity of early civilizations but also the evolution of food production and technologies to produce said food. The shift from millet based noodles to flour based dough reflects advancements in milling, agricultural practices, and culinary techniques, demonstrating how food has continuously adapted over time to the resources available to local populations

The Reason Europeans Began Consuming Coffee During the 16th Century

Leave a comment

Coffee was initially referred to as a drink only consumed by the devil and frowned upon until Pope Clement VIII tried it and changed his opinion which changed Rome, Italy’s stance. Coffee was seen as the devil’s drink because it was the drink of the Muslim and therefore by default the infidels with whom Christians had been at war for centuries. Pope Clement VIII famously stated that coffee was so delicious that Christians should cheat the devil by baptizing the beverage

How Plants Produce Food Via Photosynthesis

Leave a comment

If a leaf is magnified 1000x, green bacteria like structures can be observed, referred to as “chloroplasts,” which are packed into virtually every cell of a plant. These chloroplasts behave like bacteria, retaining their own deoxyribonucleic acid, and are only 5000ths of 1 millimeter (0.005 millimeters or 5 micrometers) in diameter. It is inside chloroplasts that photosynthesis occurs. Photons, which are tiny and rapid moving particles of electromagnetic energy (e.g. rays of light), are harvested upon the surface of the plant’s leaves, where they then enter the plant’s cells and are absorbed by the light harvesting complex located within the chloroplasts themselves. It is here that the photon is leveraged to drive the photolysis reaction, which is to split a water molecule and release oxygen, electrons, and hydrogen ions, fueling the energy transfer mechanisms that ultimately convert carbon dioxide into sugars for the plant’s growth and survival

The Caribbean Village of Biological Males Born Without Male Genitalia

Leave a comment

There is a village in the Dominican Republic called Salinas, in which 1 in 90 of the people born are born as males, with testicles, but without a penis, because of misconstrued instructions at birth. In males, the gene on the Y chromosome, specifically the Sex Determining Region Y (SRY), instructs the gonads to become testicles. This leads to the creation of dihydrotestosterone which is a stronger version of testosterone. Dihydrotestosterone transforms the tubercle which all males and females have, into a penis. Females do not make dihydrotestosterone, therefore their gonads become ovaries, and the tubercle becomes a clitoris. Infants perceived as female at birth, due to a lack of dihydrotestosterone during fetal development, later develop a penis during puberty when testosterone triggers penile growth, as it does in typical male development. Those who lack the ability to create dihydrotestosterone, as is the case with those born as males but raised as females in the Caribbean village of Salinas, Dominican Republic where it is common, are technically male, but without a penis, a condition referred to as “5 alpha reductase deficiency”. This condition is quite well accepted in this part of the world and even has a term which is “guevedoce(s)”, (pronounced “guava-doh-chey”) which means “penis/testicles at 12” in Spanish. This condition whilst common in this region of the Caribbean, it is very rare in other parts of the world

How Armor Was Decorated During the Medieval Period

1 Comment

Armor was embroidered during the Medieval period by using oil and lead paint to mark off ornate areas which would stand out and perhaps be decorated with gold or other precious metals in a process referred to as “gilding”. Gold does not easily bind to any type of metal and the only way to properly do so is to undergo a process which involves mixing the gold with mercury. Once applied, a mixture of salt, vinegar, and copper sulphate, which is root killer, makes a paste which eats through the metal leaving the painted parts untouched, and resulting in an etched piece of armor. Blacksmiths sometimes heat treated armor which turned it a blueish hue which essentially rusts the metal as it is referred to as an “oxide” and an oxide occurs when a metal comes into contact with oxygen which reacts with the metal and creates a deposit when heated to a very specific temperature, as the heat is what shifts the red color of rust to the blue area of the color spectrum

The Problem With Super Massive Black Holes

Leave a comment

Super massive black holes have a fundamental problem in that not enough time has passed since the creation of the universe to account for their massive size. This acute time crunch is because the universe has a finite value of only 13,700,000,000 (13.7 billion) years. It is theorized that the reason super massive black holes can become larger than what time permits is because they have a colossal head start due to the fact that they may be birthed directly from a cloud of gas, a phenomena referred to as “direct collapse”. These molecular clouds collapse under their own gravity, and as they collapse, fragmentation occurs as more densely packed areas collapse more quickly. Nuclear fusion begins next and a star is thus created. If a giant gas cloud collapses without making a star, it would form a gas disc instead, allowing the mass to flow into the center very rapidly, creating a black hole instead which is essentially a vortex upon an immense scale

The Reason Life Upon Earth Migrated From the Ocean Onto Land

Leave a comment

Billions of years ago when the first living organisms started harnessing the energy of the sun through photosynthesis, they began producing a waste product which was oxygen. When oxygen rises high up into the atmosphere, it transforms into ozone which is why the Earth has a thin protective layer of ozone which alongside the magnetic field, helps protect the Earth from the violent ultraviolet radiation spewed out by the sun. As plants, microbes, and fungi migrated from the water to land, even more oxygen was produced, extending the ozone layer to become much more formidable. This was the catalyst for life migrating onto dry land which occurred 450,000,000 – 500,000,000 (450 million – 500 million) years ago during the Paleozoic Era, specifically during the Ordovician and Silurian periods

The Condition of the Earth After the Chicxulub Asteroid Collision Which Caused the Extinction of Dinosaurs

Leave a comment

Immediately after the Chicxulub Asteroid collided with the Earth, heat from the fireball produced reached temperatures of 5500 degrees Celsius and produced a shockwave which broke the speed of sound, causing gale force winds equivalent to a hurricane. Everything within 965 kilometers was instantly decimated. Within 11 minutes of impact, the sky began to darken as debris which had been pushed up into the atmosphere started to settle back down. As these small spheres the size of a grain of sand descended back down to Earth, they heated up upon re-entry, identical to that of an asteroid, which provided the illusion of billions of simultaneous shooting stars. The energy produced during this re-entry barrage of heat was more intense than the sun for a brief period of time and made the sky glow red, as if it was comprised of liquid magma. This debris reflected heat back towards the Earth and effectively caused the Earth to act as an enormous radiator. To add to this damage, wildfires began sprouting up due to the intense temperature which caused heat and smoke to fill the atmosphere, compounding the damage already done. Strong winds helped perpetuate these fires and because so much of the Earth was affected, it only took a few hours to become globalized, engulfing the entire Earth in a mass fire which burned hotter than a regular fire due to the inability to dissipate heat sideways. In addition to this, gypsum which contains sulphur, blocked the sun and cooled the Earth over the long term. Gypsum had a seismic effect upon the world’s oceanic ecosystems as ocean acidification occurred due to sulphuric rain being produced by the gypsum within the atmosphere. The reflecting of the sun caused 75% of all plants to die as the Earth only received as much light during mid day as what is present during a cloudy, moonless night of the modern day

The Insect Used to Produce Ink Throughout History

Leave a comment

The andricus kollari wasp in particular has played a significant role throughout human history as it is one of the main ingredients of ink. Crushed andricus kollari wasp galls are crushed and mixed with water, then added to crushed iron sulphate and gum Arabic to produce a cost effective and extremely long lasting ink. This specific type of ink is the most important ink used during the last 1000 years of European and subsequently western history as its indelible and essentially ever lasting whether just written or having been dried for hundreds of years. This incredible ink was used to write the Magna Carta and the American Declaration of Independence, has brought forth the recorded musical genius of Wolfgang Amadeus Mozart and Johann Sebastian Bach, was used to produce the artwork of Rembrandt Harmenszoon van Rijn and Leonardo da Vinci, and was utilized to produce the theories of Sir Isaac Newton and Charles Darwin
