cholesterol is a macro phenomenon.
Every doctor and scientist you have ever met in you life is a complete idiot. Yes, even the researchers. Cholesterol contains far range signalling proteins, which they are encapsulating. You shouldn't be taking anything that fucks with cholesterol.

ive been eating 4 eggs everyday for at least 6 months, and my HDL went up from 67mg/dL to 73 mg/dL. My LDL also went up from 124 to 149mg/dL.

Overall cholesterol is up from 200 to 229mg/dL

This is actually an important question to answer because cows cause a lot of environmental problems and people really should be reducing its consumption and adding an egg to the plate instead.
An egg added to a meal should be more common, whether it’s beef, chicken or fish.

Eurofag here learning mathematics on my own, on 6th grade geometry now. My question is, since I'm learning on my own, sometimes I need feedback on the work I've done to know I've solved/worked properly, where should I look for it? Should I just look for a tutor? AI? Here? Let me know.

Khan Academy is good for self assessment. KA has interactive exercises that offer immediate, specific feedback. There's no problem if you skip their videos and use your textbooks. You will learn to use textbooks better if KA exercises force you to do so

The vast majority of my professors suck and so do their lectures. I've learned almost everything on my own from textbooks. I should agree with

At an early stage I grew lazy because I didn't feel challenged. When I went to study for one semester in a bigger university as a exchange student, I find myself really motivated and productive after encountering with many other people who were seriously committed in their education and I could compete with (in a healthy way, of course).

Later, I could get a good source of feedback and support from math communities (those which are willing to help you and are not a mere circlejerk). You could find those communities on Discord, Reddit and Telegram. I encourage you to look for them.

Thank you everyone for you feedback, you're very nice. <3

I think if I ask you to bring 5 examples, you'll fail. Some tech, like thinsulate did indeed come from NASA to regular market. Also some explosives. Maybe those stupid convertiplanes will do.

But the shit with military is that they want robust and dumb solutions at big scale. And they are not limited in money. It's not always goes well with innovation. For example civic airplanes are much more fuel-efficient then military. FPV drones was initially developed for fun races (while military was making bullshit like Black Hornet). Commercial DJI Mavic is used for reconnaissance.

“Alien life exists elsewhere. The odds are just too good.”

“But alien life visiting us? No. Impossible. It could never happen.”

Are scientists just retarded?.

“No you can’t come here. We’re off limits. No way no how. Cope.”

It’s fucking weird.

Do scientists not consider successor theories to our own limitations? Do they think our limitations are everyone else’s limitations?

>it's extremely unlikely.

Assuming we're a roughly typical example of life rather than some extremely extremely extreme outlier, I don't think it's unlikely aliens much more advanced than us exist and know about us, or at least about life on earth. What is unlikely is that we'd know about an advanced probe sitting somewhere in the solar system monitoring.

I read it and I still don't get it. Do we have time travel or not?
12 replies omitted. Click here to view.

>>16871556
Special relativity has busted time 100 years ago. Let c>0 and Q(x,y,z,t):= c^2t^2 -x^2 - y^2 - z^2. SR (the first two pages of any SR manual) says: if any two observers are in inertial motion with respect to each others and if they witness two events A and B occurring at dates t_A and t_B, at locations having coordinates (x_A,y_A,z_A) and (x_B, y_B, z_B) respectively, then the quantity Q((x_A - x_B), (y_A - y_B), z_A - z_B, t_A - t_B) has the *same value* for the two observers. This instantly destroy time (apart proper time which applies to single objects only) since for any real number u the hypersurface P_u:= {(x,y,z,t) | t = u} of "events occuring at time u" becomes dependent of the observer (changing the reference frame changes even its direction, making it de facto fictional). The so-called "Andromeda paradox" is nothing but that fact at large scales.
>>
>>16871556
To travel through time, one must understand what it is and how it functions.
Humans understanding of time changes as we discover more about our universe. Currently sciences models of the universe (quantum mechanics) state that time is an independent factor from space. The problem with most time travel examples is they use loopholes in mathematical principles to try and justify the possibility. As science changes, so to do the hypothesis's. Ultimately the only way to travel through time that is verifiable via the scientific method is going from the past into the future.

>>16871588
>It's a man made concept
No and yes. Time is a clear force on our universe humans have observed. With or without humanity time will still exist. The perception of an object is not the object itself.

it's actually pretty sad how bullshit this is

they used a "meta material" as a delay line material, but they did an inverted delay. seemingly its more solid state than just an analog delay, but they had to use so much control logic to pull this off that I really doubt this is any better than a programmed DSP which can literally do the exact same function

the judge did everything right, this decision is what actually destroys dependable jurisprudence because you can now just hide things from shareholders and get away with it, but I guess it's more important to let companies do whatever the fuck they want. Tesla could've just said they think these goals are very achievable but he still deserves all the money and it would've been fine. Absolute clown show.

I’m a grad student. I used to love math. I thought it was so beautiful and I’d just spend my free time looking through math articles on Wikipedia or listening to YouTube channels with great explanations and just be at awe at the beauty I was seeing.

I look at the same concepts and now I feel numb. I’m not even angry the joy is just gone.

Academia took something I found creative and beautiful and turned it into a source of stress and mental anguish. That’s evil incarnate

Like orcas for example, orcas are viscious psychopathic hunters but never attack humans in the wild. Orcas have high intelligence yes, but I know there's other examples too, like Polar Bears are the only species that actively hunt humans, and lions are naturally scared of humans. How does something like that happen? I get the logic that all the brazen animals who approaches humans gets killed, therefore only the animals who are wary of humans survive, but do they really "teach" their offspring that, or is it something inherent biologicially? Just a question I was thinking about. How does evolution work in the way that it makes certain species wary of other species?

Learn your history. The "classical" view of animals is as objects that move. Attributing the ability to think and feel to them is a massive step that many still haven't taken. However, animals ARE stupid. You aren't wrong there.

Same with children, they still don't have full human rights because of that "classical" assumption.

humans are brutally retaliatory, just look at what happened to wolves, the only ones still thriving are the ones we turned into our slaves.
Animals that mess with humans are usually too stupid to know better, breed too fast to care, or have starvation madness.

I skimmed the "Linear Algebra, Data Science, and Machine Learning" from the series. It looks promising. Covers everything, a lot of exercises, has programming exercises, has solution manual for 1/3 of the problems on website, 1 chapter for graph theory stuff.

The main issue is the typesetting imo, feels like they try to cram as many things as possible on a page, making it hard to read. Doesn't look like older springer books. But it could be just the pirated version. Also a lot of the figures like the plots needs colors. So you can't just print the book B&W.
