  1. Please tell me this is sarcasm

  2.  @Shakespeare1623  0:38 "The spread has grown to 50 micrograms, or 50 parts per billion" The masses weigh 1 kg (1 billion micrograms), and have diverged by 50 micrograms. That's why he says 50 parts per billion. Yes, 1 microgram is a millionth of a gram, but he wasn't talking about things that weigh 1 gram.

  3. The pound is defined in terms of the kg.

  5. A bit over 1s as the current propagates at just under the speed of light

  6. I think it's a mixture of 2 distributions, the reason being that the formula p=1/n only works for n>50

  7. Wireless energy uses electromagnets to transport charge. Just like a charge running through a wire creates a magnetic field, a changing magnetic field can induce a charge. Teslas innovation was to tie the changes in magnetic fields to a resonant frequency. The problem was, there was absolutely no use for teslas technology at the time.

  8.  @rosstemple7617  the electrons are oscillating back and forth due to the electric field. These electrons collide with the protons in the light bulb filament, transferring energy to the protons. This occurs many millions of times a second, causing the filament to heat up and produce light. Yes, the bulb does use up some of the energy of the electric field, but it’s being maintained by the battery.

  9. It wouldn’t be a world of no earnings surprises but one where every over performance is met with an equally bad underperformance As it stands though, the market on average tends to underestimate earnings performance

  10. Current is only produced by a changing magnetic field. A static magnetic field does not provide charge to the circuit.

  11. A microgram is 1 billionth of a kg

  12. It’s pretty easy to know if it’s going to snow, as all you need to know is if it is positive or negative.

  14. Yeah because your bought up on it. No one using Celsius has that problem.

  15. Infinity is not a number, you can however measure it’s relative size - just not in the normal way we’d measure size.

  16.  @We-Do-NOT-Consent-303  cardinality allows us to distinguish between infinite sets of different sizes.

  17. How does a battery work? You will need to understand redox reactions (reactions that involve the exchange of electrons). Essentially you have two “half cells”. One “half-cell” contains a reactant that will lose electrons (oxidation) and the other contains a reactant that will gain electrons (reduction). The two half cells are connected by a salt bridge. Nothing happens yet. But if you attach the wires to the terminals (each terminal only connects to one of the half cells) we get a complete circuit. The potential difference between the cells induced a current that will propagate through the wire. That’s a simple look at it, if you want to know more look up “galvanic cells”

  18. I’d there just a magnetic field sitting there hovering around the battery? No. A magnetic field is only induced if current flows through the wire.

  19. Why is it connected to the terminals? 1) the sides of the battery are insulated. 2) as explained in my explanation of batteries, batteries are made up of two half cells. They must be separated, and it’s simply a design choice that the terminals are the only places you can connect to

  20. Why don’t they start fires? They do if you puncture them. The reactants are no longer separated which could be hazardous

  21. Waxes are interesting things. The medium only needs to move a few cm back and forth but the energy can be transmitting at the speed of light

  22. What is with this sentiment? It’s always idiots who don’t understand a thing about electricity that believe that Teslas work was both unbelievably brilliant and lost forever.

  23. It's stupidly easy. Metric is the easiest measuring system on the earth, no need to remember the ratios between measurements, you just need to know the acronyms. Celsius be Fahrenheit is more of an arbitrary choice. Every argument for 1 can be used for another, except in science where Celsius is superior because it is the standard used by most of the world (and Kelvin is calibrated to it).

  24. Not even bogo sort is that slow

  25. Rods from God would be great against small nuclear powers like North Korea which mainly relies on land based missiles.

  26. Because there is no physical place for the electrons to move. The electrons need to be able to move to transmit the current, though the current travels faster than the electrons because it’s a wave.

  27. It sounds like a very great expiriment tbh. It could have alot of implications in medical science.

  28. Probably nothing compared to the moisture already present in the air

  30. Have you ever used Celsius? It’s just as easy to use, and if your doing any calculations you don’t need to convert to a different unit (as most thinks use Celsius as a base)

  31. Random does exist.
    1
  32.  @dankduelzperuvian  unpredictability is the only quality necessary to be called random. Heisenburg's Uncertainty princible states that it is impossible to predict both a particles position and it's velocity. Essentially, no matter how you measure, you cannot predict an outcome until you look. Randomness does exist. In fact, it's probably what lead to the creation of the universe itself.
    1
  33.  @dankduelzperuvian  yeah... so what if particle position = particle position. It's unpredictable, and a particles true position can only be fully known when you check. To repeat myself, randomness just means unpredicatblility. True ramdomness means unpredicictability even when you know every initial condition. Heisenburgs Uncertainty princible is one of many proofs that you cannot predict everything, therefore true randomness is real. QED

  35. Live in Australia, no Ned to worry about negatives here.

  36. You are missing the crucial thing: electricity can travel through air. That’s why it’s 1/c. Sure, it would be a tiny amount that would barely light up the bulb, but it still would.

  37. Doing these calculations anywhere in the world will give the same result (to a tiny degree of inaccuracy)

  38. Because it’s just as, if not even easier to use than Fahrenheit, and it’s convenient for global conversions. Scientists in the US use metric, it’s only the public that doesn’t.

  44. It didn't come at the costs of our humanity, it came at the costs of rabbits, which are probably a quadrillion times less significant.

  45. Gravity doesn't effect mathematical equations
    1
  46.  @DonParlor  The equation was: x(n) = A * x(n-1) A is the fertility of the rabits (or as this video calls it, it's their growth rate). Therefore, different gravitational fields would just need a tweak to the A value. Your question is kinda like asking if Pi would change in higher dimentions. The constant is... well.. it's contstant. Nothing can change it.

  47. Hopefully not

  48. That’s the point. You can’t list an uncountably infinite set of numbers. The word “uncountable” is stupid, there’s no way to “count” an infinite set of numbers. Howsoever you can in a sense list them, or at least write a set of rules that will list them. For uncountably infinite numbers, no such list can be made.
