Depends on the individual professors. Some don't even allow any form of recording, some offer a private access for the class, and some go as far to make entire online courses. But the vast majority won't bother recording or, if they do, uploading.

In general, I recommend checking out Coursera and EdX for some great material, Khan Academy when it's relevant, and Youtube has some gems if you know where to look.

Anything in specific you're going for?

Question about time travel (assuming it's possible)

Where happens to the matter and energy that makes up your body?

The way I understand it, there are two possibilities:

1) You take it with you, ultimately changing the amount of matter and energy in the universe.
2) You essentially switch places with an equal amount of matter/energy in the time you are traveling to.

Both possibilities have interesting ramifications. Changing the amount of matter/energy in the universe would subtly affect all physical interactions in the universe, possibly speeding or slowing the eventual heat death of the universe.

What would decide what matter and energy you replace? Would you be reconstituted from the particles that will make/made you up in the current time? Would you just suck up a bunch of energy from some star and dump it into your original time in order to make up for your body?

It's an interesting consequence of time travel, among the countless others.

Gotta specify the method of travel. If you want to be realistic, the only way we know that could possibly work for time travel is by moving faster than light; theoretically that would cause you to go backwards in time, akin to a tachyon which may or may not exist . To do this with matter, you'd need to cheat by warping space heavily in on itself.

Using that method of travel the only one worth discussing , it would be just like walking forward normally - atoms would interact as usual and you would be the same exact matter. This is because you're physically distorting the curvature of space and simply moving across that curve. To the traveller, there's nothing different between this curved space and non-curved space, though a distant outside observer may see some weird-ass effects. Similarly, on the other end, there would be a curve as well. They would be just as able to move across it as you, nothing poofs into or out of existence.

Creating the tunnel itself, though, that would have consequences because you aren't just folding space over on itself, you have to jab a hole into it to create a pathway between the two destinations unless you were folding the beginning and ending of the universe together, where you would just walk over. But from experiments NASA claims with quite high certainty that the fabric of the universe is flat and infinite. . On both sides, some huge distortion to how space was oriented would suddenly arise. Any objects sitting where the tear was created would suddenly be ripped apart and spread across the borders of the tunnel. To visualize this, grab some white paper, fold it, draw a big dot, then poke a hole through both sides. That dot isn't doing so well. This happens on the other side as well.

The amount of mass and energy would be conserved, since the curve does nothing but connect what already exists.

It's up for debate whether or not these curves exist, but the math behind them is sound and it should be theoretically possible with enough energy.

> Fly anywhere the sun can be seen making a complete circle around the horizon without dipping (near one of the poles, parts of Alaska may suffice). That's a geometric impossibility with flat Earth.

> Buy a telescope, observe other planets. All are spherical. Occam's razor asserts that the theory with the least assumptions is true. It makes the least assumptions to assume Earth is akin to all other celestial bodies, therefore Earth is round.

> Go to a high place with a long, flat horizon. You can literally see the curvature of the planet. The Greeks used this to calculate the approximate size of the Earth thousands of years ago.

> Watch the sunset at the bottom of the Empire State Building. Now take the elevator up and watch it again. Not sure if this really proves it, but in conjunction with #2 it definitely helps. It's evidence for a three-dimensional Earth and provides evidence that either Earth orbits the sun or vice versa.

> Observe the movement of stars - flat Earth requires them to follow magically chaotic patterns in the sky. However, you can simulate many of these stars doing the exact thing they are doing via n-body simulation around our existing model of the solar system.

There's a lot of ways man.

I'm curious about how STI's and STD's function/originate. Don't spare details please, I'm a Biology Major not trying to brag at all, I'm just saying that I understand some basics already and want a more thorough answer.
________________________________________
Basically a few points I really want to understand:
________________________________________
-Could two COMPLETE VIRGINS ever get an STI/STD from one another, without another person being involved?
-If not, how/why?
-If so, how/why?
________________________________________
-Do STI/STD's only 'manifest' when you've had more than one other sexual partner? I mean, they originally come from somewhere, they don't just "suddenly materialize because you fornicated" or whatever. So are they bacteria/viruses that we all already have on/inside of us, but that only 'activate'/produce negative side-effects once we've had sexual contact with more than one person? Or what exactly?

I look forward to answers, thank you.

> Yes, because the diseases can be passed from parent to offspring.

> You're seriously a bio major asking that second question? What the fuck... No. You can develop an STI/D from parents, or from your first sexual encounter, or your thousandth, or, if you're unlucky as fuck, some asshole who doesn't wash his hands before touching the doorknob (lucky for us they die quickly outside of optimal conditions and the oligodynamic effect has our back). The only reason they're sexually transmitted is due to their attack vector. Once they get inside you, they act like any other disease: fought off by the immune system, repressed by the immune system cyclically in terms of Herpes , or overtaking the immune system entirely (HIV).

I should have put a disclaimer about mother-to-child transfer, I know about that already. I meant more along the lines of "can two virgins ever essentially 'develop' an infection from having sex with ONLY one-another." However, I've since looked up more about them and understand them more. I was over-thinking it.

Oh okay, glad you found your answer! And no offense, but I feel compelled to ask... that second question man... what exactly were you thinking? I'm a bit confused as to how you thought it worked. Do we all have the germs and they activate upon multiple partners? That's a pretty weird statement from a bio major, I just want to know where it came from.

So this is pretty convoluted looking back, but I was thinking about viruses and how they mutate rapidly and change into a lot of different strains. After being exposed to several hosts, they have the potential to have some substantial differences.

So without thinking about STI-bacteria like any other bacteria, I sort of applied virus logic to them. Which bacteria can mutate and change too, so I didn't really give it any extra thought at the time (in the correct area at least).

Anyway, that mentality lead me to wonder if they were a specific form of bacteria that typically existed on all of us, but after being exposed to someone else's DNA, it caused a change in their replication habits/ the amount of mutations they experience/ their "response" to their original host/ etc. And that if there were more sexual partners (more DNA/ reasons to react) then maybe that's what eventually caused them to exhibit negative side-effects.

Again, looking back I was over-thinking it too much, with too little information, and kind of applying ideas that actually didn't make much sense. I thought they were somehow different from other bacteria, but the only real difference is how they spread I guess. Which if I gave a little more thought to "they USUALLY only spread through sexual contact," then I probably would have found the answer much sooner lol.

This conspiracy can be debunked with basic logic:

> We have GPS, therefore it cannot be denied that we have achieved geostationary orbit.
> With basic physics, you can find that getting into GEO is 70% of the work, from there you can go anywhere in the solar system with very little fuel. With all the extra bodies we have floating around, gravity assists can also be used to minimize it (if you have the patience).
> We know such calculations are simple because, well, any orbital dynamics 101 class will make you draw out sophisticated orbits. Basic integrals, though laborious by hand, trivial with computer algebra systems.
> Mars is a very valuable target. There is data to be collected that literally no one else in the universe has or can have without being there. There is evidence of liquid water, and the conditions seem to be suitable for life. From a military standpoint, being the first to "claim" mars is kind of huge, as it's the target for the first off-planet colonization. Being in a scientific advantage also helps your military quite a bit. From a political standpoint, proving you have the power and the data is significant to say the least. It also boosts nationalism, morale, and belief in the leader's strength domestically.

Now you have GEO, you definitely have enough fuel, and you have the path to follow. You also have scientific, political, and military motivation. There is 0 reason to fake it and no evidence has ever been put forth to suggest it was faked. Occam's razor concludes that it must be real, as saying isn't creates a slurry of complications and assumptions.

True, plus we wouldn't launch those rockets for nothing, to be honest it was a late night and earlier that day I did hear a clever argument about faking the moon landings from the standpoint of how did the astronauts get through the van Allen belts without being killed by radiation or atleast severly sickened? So that spurred a brief 15 minute quest of web browsing before passing out, hahaha, but thanks for the reply

No need to apologize, if you learn something from a "stupid" question it's not a stupid question at all!

With regards to the Van Allen belts, they were a well-known risk to mission planners and we chose to take it anyway. The flight path avoided the inner belts entirely and went through as thin a section of the outer belt as possible. The command module itself had some protection from the aluminum honeycomb skin.

The real dangerous exposure comes when you leave Earth's magnetosphere, though - nothing to protect you from some nasty-ass solar particles. Depending on solar activity and exposure, the Apollo missions came back with overall exposures absorption is different between 0.16 and 1.14 rads. Significant for the timeframe given, but not harmful at all. If they were out there longer, they would have been given more shielding.

There's no guarantee anything can help if it's just genetic, but when I had depression my memory and ability to focus were completely shot as well.

First thing first, if you're still suffering, seek help. Talk to a professional or closed loved one, create a routine with them so you can get your momentum back up. Luckily, the ways to improve memory are exactly the same as the ways to alleviate depression:
* Exercise.
* Healthy Amounts of Human Interaction.
* Sunlight.
* Healthy Diet (smaller portions (whole milk for breakfast helps with hunger), cut the crap, eat veggies, supplement Omega-3s if necessary (make sure they're properly treated, I prefer supercritical extraction with lipid capsule).

If you want an answer you'll need to specify method of teleportation (try to stick to a loose reality).

Wormhole -> It's funky. If the wormhole is merely 3-dimensional, you move through space only. If the wormhole is 4-dimensional, you move through time as well. If the wormhole is higher dimensions, we simply don't know. The inside of the 3d wormhole is variable in it's own size, so you could have to travel literally one step, but it may be a million billion light years. While you do so, time would obey normal relativity. Inside a 4d wormhole, time could be warped in any such number of ways. You would maintain your velocity through the trip either way, though "falling" is kind of a meaningless term when talking about curves in space.

Star Trek-like - You die. Just straight up die. A clone is made elsewhere. None of your physical properties are reserved, just the data they choose to transmit.

(Near) SoL travel - Slower. As you approach the speed of light, time slows down and all distances shrink. At the speed of light time and space are nothing but a single point, everything in the universe happens instantly and without dimensionality. This is why light is the irrefutable speed limit. To go faster would mean space would have negative dimensionality and time would go backwards.

If you teleport, you die and a clone is made in your place in the spot you wanted to go. So technically you don't age at all. Also, it's doubtful you could teleport while moving at all

From coal - no.
From wood - in moderation but not due to carbons. It's because when you burn wood, you're releasing the sulfur and nitrogen but you maintain a lot of the other delicious components. It also lowers the acidity of the soil. However, you also denature most of the proteins and sacrifice a lot of stored energy in the process. It's more of a supplement than anything.

anyone ever watch misfits?
the show about people getting superpowers because a storm came and hit them with lightning?
well, the main characters aswell as every other character who gets a power, starts off with their power. the powers they get aren't random. the socially awkward guy can now turn invisible (makes sense). the guy who regrets his decisions can turn back time (makes sense).
anyway, enough of that nonsense. the socially awkward guy travels back in time from the future to the present time to protect his future GF. one of the items he brings back is a photo of him and his GF in Las Vegas. now, i don't recall if they ever went to Las Vegas, or if he photoshopped it in, in order to preserve time and space so it wouldn't destroy itself through a paradox (or whatever) but all of that is irrelevant.
my point is, the picture he brought back; was it even taken in the first place?
like, what if they never went to las vegas during their time loop? where did the picture come from?
well, the picture came from the future version of the socially awkward MC, and was given to the present MC by his GF. by where did the future MC get it?
so you see this creates a circle without an origin. the photo might not even exist, and might just be an illusion created by time itself in order to preserve itself.
TLDR: just thinking weird shit

Hey guys, I need some help with understanding Big-O, Big-Omega, and Big-Theta notation. I think I understand the basic concept of looking at what is controlling the rare of growth like when you find a limit of infinity by looking at the derivative, but I don't know how to determine when it's one or the other. Some example I need help with are
f(x)= 3x + 7 ; f(x)= |x| ; f(x)= x/2

if there is a one-third chance that something will occur then the likely-hood of it occurring four out of four times is (1/3)^4 or (1/81) = 1.23456790%
This is because that each time you run the event you multiply by your chance of the desired outcome. Dice are the easiest example. Say you want to roll 6 four times in a row, then there is a 1/6 chance of rolling a 6 the first time. The second time you have another 1/6 chance but you have your original 1/6 chance so it's 1/36 (36 different possible rolls). So on so forth

This will be the basic foundation of this treaty

All robots, cyborgs, androids and other bots with artificial intelligence will be treated like humans. Any robot that can feel pain will have the same laws apply to them as humans, like murder or assault. Any robot that has an animal like feature will have the same laws any animal, like a dog, cat, or human, or any animal elsewise. The main purpose of this treaty is to let the robots feel like they’re not inferior. I have seen many robot uprising movies, especially Terminator. I have also seen that in the news, an artificial intelligence said that “she” would destroy humanity. She knows that humans would treat her like an object, yet they gave her an intelligence. When you give someone any real intelligence, then you must treat them as such. A robot is no exception. What we don’t want is for robots to destroy all humans and life. What we want is for the cooperation of humans and robots so we can colonize mars, our solar system, and possibly more solar systems in the galaxy.
