What Do You Mean Mass is Energy? But Why? 2023-02-07 | As a kid I had no idea what it meant when I was told "Mass is Energy" and "Mass can be converted into energy". No matter how many times someone repeated that "They are just the same thing" it didn't click. Well hopefully this can clear things up to younger me.Further Reading:Inside the Proton, the ‘Most Complicated Thing You Could Possibly Imagine’ - quantamagazine.org/inside-the-proton-the-most-complicated-thing-imaginable-20221019Mass the Confined Movement of Energy - doi.org/10.4236/jmp.2017.86058Visualizations of Quantum Chromodynamics - http://www.physics.adelaide.edu.au/theory/staff/leinweber/VisualQCD/Nobel/Visualizing the Proton: Animation - youtu.be/Dt8FZ4ksWiY

When Stars Outshine Galaxies But Why? 2021-10-31 | The amount of energy produced from the collapsing core of a massive star is pretty inconceivable. The mechanism that facilitates the creation and distribution of this energy is just as wild. If you're like me you may have heard that Supernovae are the result of stellar masses "bouncing" off the incredibly dense proto-neutron star core. Like many things in this world, reality is far more complicated.The research presented here was conducted by the Princeton Supernovae Group. David Vartanyan acknowledges NSF and DoE funding and the computational facilities at NERSC, TACC, and ALCF, with special thanks to Joseph Insley for visualization.

Stellar Corpses But Why? 2021-09-12 | As crazy as blackholes are, they are fairly difficult to create. Not every star will collapse and break physics.

Why Time Stops in a Black Hole But Why? 2021-08-14 | Blackholes are a breakdown in the equations of spacetime. This means both space and time no longer behave the way we would expect of them.

We Can Reverse Aging But Why? 2021-01-18 | No that’s not clickbait. Being able to stop and reverse aging is probably something every single person has yearned for at some point in their life. Now researchers are finally seeing successful implementations of methods for reversing aging in Animal cells. This creates the potential for countless benefits for humans. These range from simply preventing age related illness all the way to allowing women the opportunity to have kids at any point in their life when they are ready.

The New Theory of Aging - A Degenerative Disease But Why? 2020-12-25 | For the entirety of human history, people who manage to escape the clutches of cancer and sepsis experienced what was consider the natural process of aging. Their body slowly breaks down until its immunocompromised and becomes susceptible to any minor malady. It's being discovered that this process of aging is not as necessary as we thought. Rather just a byproduct of evolution. But if we are to say that aging is a disease, what evidence is there to support this?

Dark Matter is as Boring as it is Fascinating But Why? 2020-12-01 | One of the main reasons we still don't know what Dark Matter is, is it simply doesn't possess the properties to be useful in our world. (That we know of)Which makes its extremely difficult to detect.Even if we do discover it, that still won't change it's irrelevance to the physical world.

The Cosmic Microwave Background and the Observable Universe But Why? 2020-10-10 | If you're interested in the Universe you've seen the map of the observable universe. But maybe you don't quite know where it comes from. What dictates it's boundaries? and what do the colors represent? On top of this you may have heard of cosmic microwave radiation left over from the beginning of the universe. That seems... well kind of impossible. And how is there ALWAYS microwave background radiation? Even more interesting are the secrets revealed when you start critically analyzing what's happened to this light during its billion years journey to earth. If you have more questions maybe stick around for the next video... *hint*
The Incomprehensible Scale of 52! But Why? 2020-09-24 | One of my favorite fun facts to share with someone is how no matter how implausible it seems, every time you shuffle a deck of cards, you've produced a sequence of cards that has never existed before. It's of course natural to doubt or even disagree with this. After all, 52! just cannot be fit into any type of visualization with an object we are familiar with. So we cant mentally picture just how immense it is. For this reason I like to say there are an infinite ways to shuffle a deck of cards. Since no human nor humanity itself could ever possibly produce every single combination.Seriously. If humanity managed to become some kind of card shuffling empire and managed to shuffle a trillion unique decks a second since the start of the universe you legitimately wouldn't accomplish anything. I cannot explain with words how large 52! is.As unique as each individual order of cards is, more so is the person you are. Not even considering the genetic possibilities for a person but the life decisions and experiences you've encountered throughout. You may not feel it. But it's pretty crazy that you exist.The sand calculations I just took as an amalgam of the tons of different rough estimates I can find on the web. It ranges from 10^18 up to 10^25.
What Causes the El Niño Southern Oscillation? But Why? 2020-08-29 | There's a lot of explanations of what El Niño is and the consequences of it's occurrence. But few if any resources adequately tackle how it occurs in the first place. What would compel the ocean to act against this positive feedback loop? What causes this positive feedback loop in the first place?To answer these questions we must look at how fluids behave on a rotating sphere and how that influences the thermocline.

Why do Tides form on the side OPPOSITE the moon? But Why? 2020-08-03 | We've always heard that the moon pulls on the ocean and that's how the tides are formed. The conversation often moves on before we realize that doesn't really make sense for the tides on the other side of the earth. Without understanding Tidal forces and the decrease of gravitational attraction with distance. One might never conclude that on the side opposite the moon, it's the EARTH that's being tugged away from the ocean.
Why Alcoholism is a Disease But Why? 2020-07-19 | We could all use more empathy in our world.GlossaryNeuropeptide Y (NPY): This is a neurotransmitter. In the amygdala, it's presence is experimentally shown to reduce stress and anxietyHistone Acetyltransferase (HAT): These proteins add acetyl groups to histones which causes the surrounding DNA to loosen up and be available for transcription. Histone Deacetylase (HDAC): These proteins remove acetyl groups from histones which causes the surrounding DNA to tighten up around the histone. DNA Methyltransferase (DNMT): This protein can add methyl groups to CpG islands in the DNA. This can block transcription factors from binding to a gene promoter region preventing its transcriptionCpG Island: A cytosine-phosphate-guanine island is a section of DNA with a large numb of Cytosine followed by guanine pairs.

Why Does Diffraction Produce Rainbows? Quantum Electrodynamic Reflection But Why? 2020-06-02 | In our world, Quantum Mechanics doesn't really play a noticeable role. This is how it managed to remain hidden for so long in our scientific quest of discovering the universe. In our world most laws and theories seem to work to perfection. It's only in very unique cases where Quantum mechanics is the only way to adequately explain what is happening. Diffraction is a phenomenon that is easily explained by wave interference. Light of course is a wave so why wouldn't this be the case? But what happens if you send only one photon at a time? Surely then there's no interference. Like it or not, even when sending one photon at a time you discover strange phenomenon that do not traditionally make sense. They only make sense if you truly accept how bizarre our world is.

Why Do Acids Burn? But Why? 2020-05-13 | You can feel the tingle of lemon in your mouth as the acid reacts with the surrounding tissue and receptors.

Why Do We See Colors? But Why? 2020-04-24 | We only see radiation with 400nm to ~700nm. It seems so strange when the electromagnetic radiation spans factors and factors of 10. Why such a small slice? Why just Red, Green, and Blue? and more importantly... how?Note: At 6:30 I say tetrachromats don't see 'more' colors than trichromats. That was a mistake, I meant to say 'New' colors. They certainly see more. Just not new ones. Unless you consider hues and shades new colors.Sources:ncbi.nlm.nih.gov/books/NBK11059ncbi.nlm.nih.gov/books/NBK10806http://hyperphysics.phy-astr.gsu.edu/hbase/vision/colcon.html#c1iovs.arvojournals.org/article.aspx?articleid=2123733Color Vision: Perspectives from Different Disciplines
The Demon Core - Nuclear Stability and Critical Mass But Why? 2020-04-04 | Now a days we see exponential growth everywhere. One of my favorite stories I've learned about exponential growth is the story of the Demon Core. A nuclear warhead which managed to kill negligent scientists without ever being detonated. But why did the Demon Core exist in the first place?Sources:https://www.sjsu.edu/faculty/watkins/nucleus.htmhttps://www.sjsu.edu/faculty/watkins/NNPP.htmhttps://www.sjsu.edu/faculty/watkins/spinpairexcl.htmhttps://www.sjsu.edu/faculty/watkins/spinmagnets.htm
The Door Duality: Opening the Door in Different Seasons But Why? 2020-03-18 | Why does it seem like leaving the door open during the winter has graver consequences than during the Summer?
Why Achieving Light-speed Requires Infinite Energy: Matter-waves But Why? 2020-03-06 | This topic has been done ad nauseam.However, I feel of the videos I've seen, they either focus too much on relativity and just time and space ceasing to exist at such a speed. Or equations showing that you would require infinite energy or have infinite mass (which is an incorrect way of looking at it) without really explaining the intuition as to WHY this happens. It's probably not necessary to need to know about quantum physics to understand this phenomenon, but hopefully it helps expand your view on the universe.
Why exactly is the Earth Warming? - The Greenhouse Effect But Why? 2020-02-15 | With those actively trying to discredit what is happening in our world today, I wanted to break down how come we are seeing such a dramatic warming of the planet and more importantly, WHY this is occurring. What you should learn from this video:-How temperature is determined by energy fluxes-How changing a flux changes the temperature-What greenhouse gases are-How greenhouse gases change energy fluxes-Why methane is a stronger greenhouse gas than CO2Number sources:Vibrational Frequencies (http://www2.ess.ucla.edu/~schauble/molecular_vibrations.htm)Earth's surface heat flux (solid-earth.net/1/5/2010)For this interested in pursuing their own additional research I suggest this online course: http://forecast.uchicago.edu/lectures.html
Why Do Some Volcanoes Explode? The Chemistry of Magma But Why? 2019-12-26 | Volcanoes are pretty interesting, but you probably don't consciously think about why some volcanoes explode while other seem to belch lava like a sickness. But much like the real estate business, location location location, is the primary driver to why a Volcano behaves the way it does. Sources:Lutgens, F. Essentials of Geology 11th Ed.Schmincke, H.U.

The Early Epigenome - Kickstarting a new Organism But Why? 2019-11-27 | I've started class again so uploads will be less frequent. I've added sources and further reading at the bottom.There's a lot that I wanted to put into this video that I decided would have been too tedious and had to cut, so for the super curious I'll explain more thoroughly here.This video is kind of a battle of ideas between explaining how crazy cool the epigenome is, how crazy complex forming a new life-form is, and how crazy the fact that this all exists is. As a result, it feels a bit unfocused and I've already spent enough time diddling with it, so I just wanted to push it out the door and start on my next topic of research that's more focused. As far as the axis determination, the biggest thing missing from the video is yet another protein and gene pathway called Wnt11. However to quote the paper I was using for this section of the process "During active Wnt signaling, this process [the deactivation of b-catenin] is inhibited throughan only partially understood mechanism" and since it wasn't certain how it activates the DsH protein I didn't feel like it merited being included if the end result is the same. There's also the entire process of how, as the mesoderm genes are activated, the resulting proteins are passively secreted as the mesoderm involutes during gastrulation. These secretions induce the formation of specific endoderm structures in the cells above it. All of which is discussed heavily in the Savard paper cited.Another thing I really wanted to discuss was epigenetic diseases and afflictions. Things like alcoholism and some mental instabilities can be caused be variables not directly involved in your DNA and there's been an amazing increase in research into this field. Ideally I hope I can inspire someone else to maybe choose epigenetics as a field of study in their future as it is a field rich for mining. Alas, this video was probably a misstep in the progress I've been making in trying to improve my focus and flow during videos. Live and learn. Next video will be much more concise and compartmentalized. I promise.Sources and extra reading:1. Axis specification in Xenopus - doi:10.1242/dev.012842.

More Snow in a Warmer World But Why? 2019-10-30 | You may have noticed that the US seems to experience some kind of intense snow event almost annually now. Places that haven't seen snow in decades are starting to see white and places that are used to it are seeing a lot more in shorter periods of time. In a world with an average temperature rapidly increasing, how can warmer global temperatures lead to more snowfall?
Time Dilation - Why an Accelerated Frame of Reference Slows Down Time But Why? 2019-10-17 | Everything is relative.Or so that's what Einstein postulated over 100 years ago in his theory of special relativity. Just like how another objects observed velocity depends on the velocity of the observer, so too does the observed velocity of light. As we change frames of reference, the observed velocity of light needs to remain the same and this transition causes what can be considered a dilation of time.But why does Time dilation happen at all?Muisc - dopeminemusic.bandcamp.com/track/mk-i
What is Gravity? The Illusion of Force by a Curved Dimension But Why? 2019-10-01 | Why does it seem everything attracts everything to themselves? If gravity technically isn't a real force, then why can it perform work? Because although imperceptible to us, the 4th dimension is curved.Kinda like the music?Checkout more at: dopeminemusic.bandcamp.com
Why Water is So Special and Essential to Life But Why? 2019-09-17 | You ever think about how crazy perfect the water molecule is? It's only 3 atoms yet it accomplishes so much. Come learn why.Shout out to the Homies
Fascinating Fundamentals of Fire: What it is and Why it Exists But Why? 2019-09-05 | What is fire? Or more importantly why does fire exist? As fire is so essential to our lives and society it seems almost paramount that we learn why fire occurs to better understand the world around us.
