I've tried to use it but holy fuck he does not put any effort to keep it somewhat interesting for anyone who isn't autistic.

Aside from that the only other issue I have is that he can go into the nitty gritty stuff without really laying a foundation, I used it for Laplace transformations and he was some really contrived way of teaching a fairly simple subject. Sure the autists might crave the deep deep understanding of it but it really ruins the digestibility for anyone else.

I would agree, a good (pirated, hint hint libgen) book would be better, just be prepared for when the author gives up caring and goes off the rails, only for you to jump from 2x+1=3 to 3x3 matrices in one chapter (engineering books are like this in particular)

Will immortality be achieved in our lifetimes? When I say immortality I mean biological immortality. will the disease of aging and all other diseases be cured in our lifetime, or will we continue to die at age 70-100 like now? Is it just wishful thinking, how long will future humans live? How long will children being born in 2021 live?

It's a complete 50/50 and wholeheartedly dependent on your style of fighting

For example:
Hyenas, Wild Dogs, Wolves, and Humans are predominantly DEX builds who adapted their hunting style via harrassment and hit-and-run tactics.

Lions and Alligators are STR builds who adapted their fighting style via ambush strikes.

If they are forced to face each other, (in an open and limitless field) my money goes to the DEX because they don't really have to attack. They just have to keep the other guy exhausted.

>>13773258

>>13771541
If you have a weapon, DEX, since you can pretty much do an irl stun lock with a knife. Hand-to-hand you want STR, other than that reach is important so long as the difference in height makes bollocks a prime target

If we accept the truth of Skinner's ideas, we have to radically restructure society. We have to do away with almost all punishments, and openly shape individual behaviors for the good of society using reinforcement. Too many people benefit financially from prisons, policing, and the status quo for any serious reform movement to even begin.

Finally had time to post this, but you guys won't believe this.

I work with the JWST team. Not really a dev or scientist, but part of the janitor team basically.
But the whole facility is panicking since this morning!

THE JWST IS FUCKING GONE!! JUST GONE!!

Everyone came to work this morning and the place looked clean and normal except the JWST is not there! No one knows what happened. Is it theft? Did the government decide the military should take over? Some classified shit? No one knows.

We were just told by management like 30mins ago to basically go home and not worry about it. I am told to stay here with my team to clean shit up and then leave. Will be gone by noon probably after we close this place.
Not sure what's going on, but rumor is that it will be handed over to Space Force to use a surveillance satellite.

If the headline asks a question, the answer is always "no."

You are a biologist traveling through a rainforest and you are bitten by a venomous snake. Luckily you know the venom can be neutralized by licking the back of the male of a certain species of frog. You also know that only females of this species croak, males and females are otherwise indistinguishable from a distance, positioning and croaking behavior of a frog is random and independent from other frogs, and the population is evenly split between males and females and can be considered arbitrarily large.

Luckily you see a frog of this species in front of you. You then hear a croak behind you and turn around to see a pair of the same species of frog where the croak came from. You only have enough time to run and lick the lone frog or the pair. Which direction do you run and what is your chance of survival?

And what is your chance of survival?
>>
>>13771960
50%. At least one of the frogs in the pair is a guy and can be completely ignored. So you have two frogs basically, with unknown gender, half are male half are female. So yeah.

But irl this would have some more weird facets, like how often do these things croak? You might have more than 50% odds since the others aren't croaking. But obviously someone could claim the frogs only croak once a day or some weird shit.
>>
>>13771905
It's not a non-croaking frog, it's a frog which hasn't yet be confirmed to croak. Hypothetically it could croak within the next minute.
>>
>>13772349
>50%
Impossible, since that would imply a non-croaking frog is equally likely to be male or female.
>>
>>13772385
>It's not a non-croaking frog, it's a frog which hasn't yet be confirmed to croak.
Same thing. A frog you haven't heard croak can't be equally likely to be male or female since females have some nonzero chance of croaking.

Retroreflectors on the moon are completely useless. They don't actually work at all.

1) It is mathematical fact that setting up a mirrored corner can return the light from whence it came. But this would require engineering the mirrors to be perfectly flat, and perfectly right-angles. There is very little tolerance for error, because you're reflecting a signal 380,000 kilometers across empty space. Even the smallest angular deviation throws your signal completely off

2) It takes light around 2.6 seconds to reach the moon and back. During that time, the earth turns. If you do the math, it will displace the return signal by 1.2 kilometers. Not to mention the earth and moon's mutual rotation displaces it by another 10 meters.

3) The retroreflectors are really small. We know that even a columnar laser spreads out with 1/r^2 of the distance. Therefore this signal reaching the moon has a large radius, and is bouncing off much of the reflective soil around the entire area, kind of like sonar. Considering it's possible to measure the return-signal, which should be displaced by over 1,200 meters, that means the signal probably spreads out a minimum of 600 meters when it hits the moon. 600 meters square is 360,000 square meters. Thus if the soil on the moon returns just 1/360,000th's of the signal as the retroreflector, then it has outperformed the reflector, rendering the reflector totally pointless.
