No, most teachers really sucked except for my last physics teacher. But he had to follow the idiotic standard book which sucked and wasn't rigorous so I didn't understand a whole lot and performed badly.

So strange, something about memory creeps me the fuck out.

So imagine you take this drug that makes you lose a day of memory, and you spend the day doing cool shit.
As soon as you take the drug, you just skip to the next day. It’s like you weren’t even there.

If you do take the drug and go to a specific party, you will literally never experience it. No matter how hard you try you’ll just skip to the next day.
Of course to everyone else you’re fine, and there’s no way they could tell otherwise.

Let’s take this a step further, imagine you get sent to purgatory.
Let’s assume you have all your memories from before the purgatory, and you have memories gained during the purgatory, but you’ll lose those gained ones once you’re out.

Did you ever go to purgatory? What about spending a near infinite amount of time in there? You’ll never be there.

Is spending an infinite amount of time the only way to experience what that purgatory is actually like? Because any finite amount of time you’ll just skip through, like sleeping?

I was going to review Dr. Andrew Wakefield's vaccine-autism retracted article/study, but that was published way back in 1999 (was looking for something more recent). Maybe something that debunks or delegitimizes Covid-19 or the vaccine response to it, for example?...

I'm aware of Dr. Andrew Kaufman, but it seems like it is harder and harder for an established medical or science fields professional to go against the conventions of mainstream science or medicine, lest the find themselves pariahs and not able to find employment and pay back educational loans or recoup that investment, etc.

It's easier to claim that some people are conspiring against you rather than admitting to yourself and others that your research was simply sloppy.

In case of Dr. Andrew Wakefield's article, the methology was flawed, the same method would have yielded in similar correlations between vaccines and any X without proof of any causal relationship between the two, the study couldn't be reproduced etc.

Regardless of Dr. Andrew Kaufman's actual research. The vaccine-autism link was and still is a convenient excuse for parents to explain away their children's bizarre or stupid behavior instead of admitting that they suck at parenting, have emotionally abused the child or simply have shitty genes.

It's called freshman quantum mechanics (physics 3), undergrad quantum mechanics, grad quantum mechanics, and quantum field theory. Every university does that.

>follow this (lol) to death by repetition
Physics education is iterative with each iteration using more math. It's normal to repeat Mechanics, EM, and Quantum 3 three times.

>as for OP I'd suggest just googling a curriculum of a top10 university of your choice and going off suggested reading from there
Spoiler: Those are. There are 2 or 3 books for each mainline subject in physics that are canonical and used in practically every school. You can find the substitutions here.

Why? What would be the point of that? The notebook would double in thickness, wouldn't that weaken the pages at the spine?

besides, the notebook pages are already made of paper, so how is adding blank pages supposed to preserve anything?

The thing won't be falling apart for several decades at least, how long do you want it to last, op?

If you want to preserve the content for the long-term, your best bet is to scan the whole thing digitally and copy to a bunch of digital archives, in addition to keeping good care of the original physical notebook.

Perhaps you should read the wiki article again. From the same page.

>The signal itself appeared to be an unmodulated continuous wave, although any modulation with a period of less than 10 seconds or longer than 72 seconds would not have been detectable

Once again, we have no idea it was continuous or not...or if it was modulated. The equipment limited our ability to detect it.

The Big Ear, due to design and technological limitations at the time, caused this limitation.

But if you don't believe me, listen to this interview with Dr. Jerry Ehman (the guy that discovered it and wrote Wow!) where he explains (in detail) this very thing. He also laments in this interview that they lacked the ability to discern modulation.

Hyperinflation and lack of production will lead to economic collapse in the west. Fatties are responsible for the healthcare crisis. It's a leading risk factor for heart disease and many forms of cancer, which predominantly make up the causes of death here in the us. If fat people stopped being fat, it would lead to decreased demand for healthcare services, which, under a normal system where healthcare providers weren't working with insurance providers to rail the backside of the average consumer for the most amount of money, would mean lower prices. However, that's not going to happen anytime soon, meaning that the industry is going to continue reaming people's wallets and people are going to continue being fat.
The good news is that if and when hyperinflation hits, most people will lose a ton of weight. Communism is one of the most effective weight loss diets.

Suppose every other class of complex multicellular animal other than insects were suddenly wiped from the earth.
How long would it take for one of em to evolve into current megafauna sizes? e.g. the size of deers and oxen.

We would see the rise of hive-beings. Cellular-cellular life.

I would bet that the insects would fill their niches, constrained in size by the oxygen levels of the atmosphere, and that it would take as long as bacteria took to evolve to dinosaurs/mammals for their to be anything the size of deer or oxen.

They wouldn't, they'd die out quickly due to the entire global ecosystem being suddenly fucked in the ass.

Wouldn't matter. Sentience wouldn't evolve for another 800 million years, by which time the sun will be going red giant. Even if sentience evolved before that happened it would find all the economically extricable energy and mineral reserves so severely depleted that they wouldn't be able to build an advanced technological civilization. They would probably have enough time to discover our fossils, piece together what happened, and roundly curse us before being swallowed by the expanding sphere of the Sun.
