Actually, it was Oliver Heaviside who condensed Maxwells original 20 (!) equations down to the four we are familiar with today.
A brain the size of a planet. When I first got into his equations in engineering class, I marvelled at his ability to collapse the entire e-m world into four elegant equations. The best science is always beautiful!
Maxwell was Einstein's Einstein.
Yep, Heaviside is criminally unrecognised in my opinion. Here are a few of his other major contributions to physics and engineering:
1880 - Researched the skin effect in telegraph transmission lines, and in same year, patented the coaxial cable, an invention that is vital to our modern world, finding use in areas such as internet and network connections, digital audio and cable TV signals.
1880-87 - Developed the operational calculus, giving a method of solving differential equations by direct solution as algebraic equations.
1884 - Using his newly-devoloped calculus, Heaviside recast Maxwell's mathematical analysis from its original cumbersome form into its modern vector terminology, thereby reducing twelve of the original twenty equations in twenty unknowns down to the four differential equations in two unknowns we now know as Maxwell's equations. The four re-formulated Maxwell's equations describe the nature of electric charges (both static and moving), magnetic fields, and the relationship between the two, namely electromagnetic fields.
1885 - Independently discovered the Poynting vector, defined as the rate of energy transfer per unit area of an electromagnetic field.
1885-88 - Invented the Heaviside step function and employed it to model the current in an electric circuit. He was also the first to use its derivative, the unit impulse function, now usually known as the Dirac delta function. During this time, Heaviside also coined a number of terms describing electromagnetic phenomena, many still in use today, such as conductance, impedance and permeability.
1888-89 - Calculated the deformations of electric and magnetic fields surrounding a moving charge, as well as the effects of it entering a denser medium. This included a prediction of Cherenkov radiation, only experimentally discovered 60 years later, and inspired his friend George FitzGerald to suggest what now is known as the Lorentz–FitzGerald (length) contraction, which became an integral part of Einstein's Special Theory of Relativity.
1889 - First published a correct derivation of the magnetic force on a moving charged particle, which, along with the electric component, forms what is now called the Lorentz Force. The same year, he started working on the concept of electromagnetic mass. Heaviside treated this as material mass, capable of producing the same effects, laying the foundation for Einstein's discovery of the equaivalence between mass and all forms of energy, not just electromagnetic, immortalized by his most famous equation, E = mc².
1893 - Discusses the possibility of gravitational waves, using the analogy between the inverse-square law in gravitation and electricity, a full 25 years before Einstein's paper on this subject.
1902 - Advanced the idea that the Earth's uppermost atmosphere contains an ionized layer known as the ionosphere; in this regard, he predicted the existence of what later was dubbed the Kennelly–Heaviside layer of the ionosphere. Heaviside's theory explained the means by which radio signals are transmitted around the Earth's curvature. The existence of the ionosphere was experimentally confirmed in 1924 by Edward Victor Appleton, for which he received the Nobel Prize in Physics in 1947.
Was absolutely awful. Taught pretty extensively around Tulsa schools at least. The ironic part is that Tulsa could possibly have been a major city if it had kept its course. Tulsa was frequently described as "the black New York". Just imagine a city as big as New York in Oklahoma and that was a potential future dashed away after this night.
Glad it's taught in Tulsa, because it wasn't mentioned once when I was in OKC.
Wasn't just Tulsa.
The Red Summer refers to the summer and early autumn of 1919, which was marked by hundreds of deaths and higher casualties across the United States, as a result of race riots that occurred in more than three dozen cities and one rural county. In most instances, whites attacked African Americans. In some cases many black people fought back, notably in Chicago. The highest number of fatalities occurred in the rural area around Elaine, Arkansas, where five whites and an estimated 100–240 black people were killed; Chicago and Washington, D.C. had 38 and 15 deaths, respectively, and many more injured, with extensive property damage in Chicago
It's upsetting I never once heard of this in my "Oklahoma History" class in high school ..
Yes, the man asks the officer..."minus the bike?" ..and the officer says yes. Oahu is my home, this video really doesnt quite give you the sense of how many people live this way here. I can proudly say, majority of us Locals who are born and raised in the islands do NOT feel or act like the two Hawaii Kai residents in this film. That lady who actively patrols "her neighborhood" would not be so keen or cavalier had the film crew and support crew not around. As a local, my heart and actions have gone out and will continue to do so, whether you have a home or a tent or nothing at all, all the same. We are Human Biengs. Property values go down, yes. Tourism lost, sure. When you leave this life, can you do so with dignity? Search your hearts. We breathe the same air, and gaze at the same sun and when all is said and done we all pass away. Try bieng excellent to eachother, on a human level. That alone would be a good start.
**edit. To all in here reading this, thank you for the cheers. I wish to also say thank you for the gold. Anyone reading these comments and feel that contagious, butterflies-in- the-stomach feeling is what we call Aloha. Its what real Hawaii is, and should continue to be. Aloha means we take care of our neighbors as well as the stranger. You have shown me that our world still has hope. All these comments prove that Aloha is alive and well, way beyond the shores of this island.
Every time I go there I look at them and think....if I'm ever homeless, why not here?
In Canada, the homeless travel to Vancouver from across the country because our winters are much milder. These homeless are lucky, try living outside in -32 C.
I can't stop thinking of a bbc special narrated by David Attenborough about the great migration of homeless people across Canada to Vancouver
From Spy To President: George H. W. Bush. Doesn't seem like that great of a title anymore.
Still shocking how many Americans are blissfully unaware how GHWB was a member of the CIA long before he became president.
I am Russian. I have put an X next to Putin's name back in 2000 when I was ten.
Guys, you really had to live through the ninenies in Eastern Europe to understand the scale of the comeback Putin had orchestrated. He had accumulated enough good boy points to nuke half of Russia and get away with it. He's like Reagan or Kennedy in the eyes of 90% of Russians because of his achievements.
He is not perfect, but there are legitimate reasons to like him.
That's kind of a weird argument. That is the highest rank in the CIA. You are being fed enormous amounts of intelligence and in control of the world's most successful spy agency.
Compare that to Putin, who wasn't very high ranking in the KGB.
Edit: I also don't buy the claim that Bush was "only in the CIA for a year." Bush founded Zapata Oil and was president of its subsidiary Zapata Off-Shore, which was a CIA front company.
TLDW: Grown up guys dressed up as ghosts hiding their faces, and gangsters afraid of rain. Now if this ain't a parody on life...
My wife was fired from Walmart. I believed it was a racial discrimination case. So I Googled "white right lawyers."
Your wife was fired from Walmart and your Google search got you to join the KKK? smh. Amazing...
"I CAN'T SEE FUCKiN' SHIT OUT OF THIS THANG."
first, they take away our mascots, next thing you know you're in a concentration camp.
You had to make the title all about you somehow!
My girlfriend's ex husband is just like this. Actually expected her to work and raise their kids by herself while he quit his job and went out to bang other girls. Then got pissed and blamed her when she left him. Called her a horrible mother, bad wife etc. No one in his family speaks to him anymore and he claims that's her fault too. He has absolutely no self awareness.
Wait OP did you do this on purpose?
My president has this
The TRUE story of an ALLEGED mission.
Yeah, none of this makes sense which is setting off my bs alarm.
If there were military ppl on board, where did they go after landing? Why didn't Saddam parade them around like he did with the civilians? Most importantly, why would they fly in on a 747 when they could literally drive a boat ashore at night?
Ah, the true story of an alleged event.
I'm Kuwaiti and I was wondering how did your time here change your view on the gulf war?
tl;dw: Girlfriend bailed at the last moment, he became kinda famous, a 30 something woman joined him (probably for the local fame), it was hell with terrible food, mosquitoes, etc, they left, later he went back to a similar island with the original girlfriend, she spent most of the time sick, they left, came back later 10 years or so for a kinda reunion and closure for the documentary, turns out he's been gay the whole time (seriously).
Edit: While -> Whole, thanks /u/thegodemperorofchaos
Now I have to watch this because I don't believe you.
Still a better love story than twilight
Watched it. Here's the TLDW: 18yo fantasizes about living out the Blue Lagoon movie. Childhood sweetheart can't go. Finds some 30yo woman to join him. Island sucks. She gets annoyed and leaves. He finds a better island. Sweetheart joins him. They struggle. Stay 7months. They leave and split up. Then 20 years later they return for a reunion and for the doc. Turns out he's gay. The end.
TIL that through meditation I too can level my stamina skill tree.
There's a 2014 journal article explaining the biology behind the method. He taught the method to a group. It is repeatable. Not magic. Not genetic anomaly. Controlled hyperventilation + static apnea + meditation.
Kox, et al., PNAS, 111:7379 (2014)
Dude, they told us that way back in the tutorial.
It's because he's a bullshit peddler. Look at OP's title.
Climbed Mt. Everest in his shorts.
No, he completely failed, in every way, to climb Everest. He gave up a mile and a half vertically away from the peak. Meaning he did the easiest part, and actually only hiked about 25% of Everest before he proved he was completely incapable of his nonsense claims.
Resisted altitude sickness.
Every person is capable of resisting altitude sickness. It's called "acclimating". All Hof's method is is acclimation training through auto-asphyxiation before you hit the mountain. Not exactly magic or rocket science.
Completed a marathon in the Namibian desert with no water.
By being fit, having good genes, and waterloading. Nothing magical or even complicated, just drinking enough water beforehand.
he's able to influence his autonomic nervous system and immune system at will.
Literally every human on earth can do this and it has been solidly proven in lab settings. They're directly tied to your emotions and mindset, so any form of meditation will influence them.
He's a minor genetic outlier who happened to dedicate himself to doing stupid bullshit with his ability, but instead of just being proud of it, he pretends to be transcendental. So fuck him.
Sugar is bad, junk food is bad. Government/schools are in cahoots with processed food industry and fast food. Cook at home and cut out sugar. Overall a pretty good message, but
Does not address how you can still be obese following government absurdly imbalanced food pyramid which emphasizes carbs and vilifies fat like crazy, and which most adults believe still. If it's whole grain it must be good right? wrong My heart went out to the chubby kids who were trying to exercise and watch what they ate and their parents are buying them reduced fat crap (read lots of carbs) Vilified cheese industry. You can eat at fast food restaurants, but you can't supersize it, and you need to get rid of the fries/sugary drink/chips and probably the bun.
(I watched it at 1.25x speed and it was still pretty slow)
Damn. There goes my Snickers nachos.
This should be required viewing for everyone.
