The Fallacy of Airplane Mode Disabling the Global Positioning System Tracking of Smartphones

Leave a comment

Even when Airplane Mode is activated, the Apple iPhone still receives signals from the global positioning system because this apparatus is a passive, receive only system which does not rely upon a cellular connection, WiFi connection, and/or Bluetooth connection to function. The iPhone scans and listens for satellites orbiting the Earth and calculates its relative position based upon this timing data, which means the iPhone can still determine a users location even without an internet connection, however if this is not desirable by the end user, Location Services can be disabled which theoretically turns this function off. This information is true for most modern smartphones including Android, however not all (e.g. smartphones manufactured prior to 2010, minimalistic/budget conscious smartphone designs, smartphones with custom firmware and/or enterprise restrictions like those managed by corporate information technology teams or running custom read only memory etc.)

The Reason the Earth Becomes Colder When Closest to the Sun

5 Comments

The Earth orbits the Sun in an elliptical path, meaning the distance between each body constantly fluctuates. Perihelion is the specific point in this orbit at which the Earth is closest to the Sun with this phenomena occurring near January 3rd annually. In contrast to this, aphelion, is when the Sun is at its farthest distance from the Earth, which occurs in July each year. Interestingly and counterintuitively, the Earth is coldest during its perihelion phase (when the sun is closest to the Earth) and warmest during aphelion (when the sun is furthest from the Earth). This paradox occurs because of the struggle between orbital distance and the 23.5 degree axial tilt of the Earth. Whilst the Earth is slightly closer to the Sun during the perihelion phase in early January, receiving 6% – 7% more solar energy than in July, the Northern Hemisphere is tilted away from the Sun which forces sunlight to strike the Earth’s ground at a more shallow angle, therefore spreading the light over a larger surface area and filtering it through more of the atmosphere. This reduction in heat overrides the slight shift of the Earth and Sun being closer or further away, as it is the tilt of the Earth, not the orbital proximity of the Sun which dictates both the 4 seasons as well as the perihelion/aphelion paradox. It should be noted, global temperatures peak in July because the Northern Hemisphere Continental Crust heats more rapidly than the Southern Hemispheres oceans

The Fallacy of Snowflakes Being Perfectly Symmetrical

13 Comments

The 6 sided geometric symmetry observed within snowflakes is governed by the rigid molecular structure of hexagonal ice, which is the only crystalline form water can adopt within the Earth’s atmosphere, and the reason snowflakes always have 6 dendrites (points) like a hexagon. It is a common misconception that all snow crystals (snowflakes) exhibit perfect symmetry, as most often they do not possess this characteristic. It is true in the sense that at the microscopic molecular scale, snow crystals form perfectly, but it is untrue because at the macro, real world scale, anomalies virtually always form. This occurs because as the snow crystal becomes larger, water molecules no longer attach to develop and maintain a uniform orientation. Additionally, as the snow crystal grows and expands, factors of the ambient environment begin to influence it (e.g. effects of humidity and temperature etc.) causing the snow crystal to grow one way whilst in one position of a cloud and then grow in a completely different orientation once having been forcibly moved to a different spot within that same cloud. Because of this, it is rare but still possible to find a perfectly symmetrical snowflake. This explains why despite the complex and random nature of snow crystal growth, all 6 arms must align in every case and grow along the same 6 fixed 60 degree axes. If this does not occur, the snow crystal would violate the fundamental laws of energy minimization (to become most stable) dictated by the hydrogen bond lattice (framework connecting atoms within water), which would cause the structure of the snow crystal to become thermodynamically unstable and therefore highly prone to fracture

The Hottest Natural and Artificial Temperature in the Universe

Leave a comment

The hottest temperature ever measured and/or observed was within the Large Hadron Collider located on the border of Switzerland and France. When lead particles are smashed together within this particle accelerator, for a split second the temperature reaches 4,000,000,000,000 (4 trillion) degrees Celsius which is hotter than a supernova explosion, albeit the theoretical maximum possible temperature of the universe is believed to be 20 orders of magnitude greater. Contemporary models of physical cosmology postulate that the highest possible temperature is the Planck temperature, which has a value of 1.416785(71)×1032 kelvin. Temperatures above this are believed to be physically impossible because as particle energies become larger and larger, the gravitational forces between them inevitably become as strong as the other 3 fundamental forces which essentially boils and breaks down both the universe and space time. Outside of laboratory conditions however, the hottest naturally occurring place within the universe is the quasar 3C273 (the 273rd entry in the Third Cambridge Catalogue of Radio Sources), a blazing region surrounding a supermassive black hole approximately 2,400,000,000 (2.4 billion) light years away from the Earth, with matter within its accretion disk being measured at temperatures of approximately 10,000,000,000,000 (10 trillion) kelvin, making it far hotter than the core of any star, and 400,000x hotter than the core of the sun, rivaling the conditions of the universe right after the Big Bang

The Coldest Natural and Artificial Temperature in the Universe

Leave a comment

The coldest temperature ever measured and/or observed was within a controlled laboratory experiment in Germany; an experiment entitled “Time‑Domain Matter‑Wave Lens System for Atomic Clouds”. During this experiment, physicists cooled a cloud of rubidium atoms to 0.000000000038 (38 trillionths) of 1 degree above absolute zero which is -273.15 degrees Celsius, colder than the vacuum of space, slowing these atoms to a near motionless state for a very short period of time which created a fleeting state of matter existing closer to perfect stillness than anywhere or anything else within the universe. This experiment was the closest scientists have come to achieving complete absence of motion within a controlled setting. Contemporary models of physical cosmology postulate that the theoretical minimum possible temperature is absolute zero, which has a value of 0 kelvin. Temperatures below this are believed to be physically impossible because particle energies become so tiny that all molecular motion ceases to continue functioning, allowing quantum effects to dominate, and producing exotic states of matter (e.g. Bose-Einstein condensates in which matter behaves as a single quantum entity etc.). The coldest naturally occurring place within the universe is the Boomerang Nebula, a dying star cloud located approximately 5,000 light years away from the Earth. The Boomerang Nebula has been measured at 1 degree above absolute zero, making it even colder than the faint afterglow of the Big Bang itself, yet the Time‑Domain Matter‑Wave Lens System for Atomic Cloud experiment is 26,000,000,000x (26 billion) colder and closer to absolute zero than the Boomerang Nebula or any other naturally occurring region with low heat

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

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 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 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

Inventions and Discoveries Developed Simultaneously Throughout History

Leave a comment

In 1922, a pair of Columbia University sociologists named William Ogburn and Dorothy Thomas published a paper entitled “Are Inventions Inevitable?” which stated that Ogburn and Thomas discovered 148 examples of documented simultaneous invention. This phenomena occurred in 1876, when Alexander Graham Bell and Elisha Gray filed for a patent for the telephone on the same day with Bell’s unit having a separated listening and talking piece whilst Gray’s unit having a single listening and talking unit built into a conical structure. Other notable examples include Charles Darwin and Alfred Russel Wallace who came up with the Theory of Evolution simultaneously, Carl Scheele and Joseph Priestly who discovered oxygen at the same time, Isaac Newton and Gottfried Leibniz who discovered and developed calculus at the same time, Dmitri Mendeleev and Alexandre-Émile Béguyer de Chancourtois who discovered and developed the periodic table at the same time, and Orville and Wilbur Wright and Samuel Langley who invented the airplane during the same period of time. Knowing this, it would seem that the phenomena of simultaneous invention and discovery seems to be exceedingly common for human beings throughout history
