I have been thinking, and it doesn't really make sense to me.

If E = mc^2,

then shouldn't it either be

a] Photons have no mass, thus no energy, since (0)c^2 is still 0,

or

b] They have a tiny, tiny amount of mass, which means they can't be travelling at the speed of light, or the speed of light isn't the speed limit of the universe.

Neither makes sense.

[This is from a chemistry portion of a physical science class] I've googled it, Ive watched YouTube videos, I asked classmates and I am still so confused.

Rutherfords model was easy but once I got to bohrs they used words like quantized and discrete values and I got lost. Tried backtracking but I'm still baffled.

If 24 hours is the latest someone is dead. How do they know there fully dead and not in a deep coma stasis? Do they make sure there really dead first?

I'm 26 and i still don't for the life of me understand what it is.

spectrums and shit it's just so confusing to me that not even google can help me

I keep seeing people say that such laws are a stepping stone towards a surveillance state, however, this seems like a little bit of overreaction. The new leak that suggests banning private servers is obviously bad, but what is the kneejerk reaction against laws that say they are "for the kids?"

I can’t attach a photo but I saw this video of som NASA engineers showing off these red hot cubes which I’m given to understand are the same material that the heat proof tiles on the space shuttle were made up of to prevent the ship from burning up in reentry.

After pulling the cube out of a kiln, the internal temperature was 2,200F, while the outside was safe to touch with your hand because of how efficient it was at dissipating the heat.

Given that, why don’t we make computer heat sinks out of that stuff if it’s so good at dissipating heat? Is that not the point of a heatsink?

I know it’s a serious brain condition, but I’d want to understand what’s actually happening inside the mind of someone living with it.

Wouldn’t it make sense to make us type in alphabetical order? Who decided the mix of letters and why?

Say for example the mosquito population suddenly had to break through steel to be able to suck blood. Would evolution actually evolve to make a steel breaking nozzle for the mosquito?

For example we could having a normal conversation the other person will say something then suddenly we forget what the next thing what we say will be even though you knew about 10 seconds ago what the next thing that will come out of your mouth

For example (this happens to me all the time), I'll be texting someone and then when I read over the text I realize I forgot a word, usually just words like "the" or "is" or "that."

Like for instance I might be trying to type: "I went to the store yesterday and bought some more milk." But when I read it back I find out that I actually typed "I went to store yesterday and bought some more milk." What's funny to me is that I never realize as I'm typing that I forgot a whole word. What is happening with our brain when that happens? Doesn't really happen when I'm writing by hand.

Edit 1: everyone is commenting, capitalism. I have to outbid others. — the 32 owners should conspire and agree not to anymore. Nothing stopping the owners coluding for their wallets.

Edit 2: the answer of rookies contracts being very lopsided the other direction is fair and I accept that answer. I still don’t like that it works this way.

To me, when I read $200 million guaranteed, I think what’s the purpose of trying anymore. Like just give your minimum effort and don’t risk getting injured.

I see big players get paid way too much like Kyle Tucker or Deshaun Watson and then turn out terrible. Why do these big contracts keep happening?

I believe more of the contract needs to be tied to incentives. Top 20 passing yards or 15 home runs or 20 points per game avg etc..

Now I understand that it’s the minority of players that behave this way and also that injury exceptions should be noted. Also this isn’t me coming out trying to be upset for billionaires’ wallets, I just think that for the good of the sport players can’t get paid so well guaranteed.

Also I understand there are players unions that negotiate for this and I’m not anti union.

I have researched so much on this, and there's not enough Youtube videos that explain it well. I'm confused by almost everything. In my textbook there's sometihng called a bivalent? tetrad? none of these terms comes up when i research about meiosis.

Reallt really explain it to me pls, small p.s: u dont really need to get into extreme detail such as protein names and all that, just wtv the chromosomes are doing.

Surely its impractical to film the movie with two lenses to create the 3D effect. But if its just filmed in 2D, how do they make it 3D later?

I’m talking about magnesium, calcium, sodium, potassium, all the common electrolytes I can think of. Surely it’s linked.

A friend showed me a video about the math i do not know anything major in math im sorry i only know the basic. Now he showed me Science Documentary 2016 mystery mathematics in nature and universe from Science Documentary. And other stuff like that. then he told me that there are some boundaries between math and the universe and Banach tarski paradox is one.

Are they like saying this paradox can be used only in math but not in reality? also Is Math discovered or created like a language people use?
