> Doesnt that just prove my point that some part of engineering literally is math

Not sure, maybe. I don't know enough about Control theory, what type people that writes what types of papers on it and where these are published to take a stance on it. Still, that point that you want to make is not the point you need to make. If you are able to make this point, it does not matter, these people they are in the minority. Very few engineers end up having the rigorous mathematical background to publish anything meaningful in mathematical journals.

> Not suprising, who else would you expect to do it given that other types engineers wouldnt know the necessary math

I mean, if there's an engineer that have the background to do mathematical research and he actually is doing mathematical research, then he is doing mathematical research, hence by definition it is welcome on this forum. It is not a problem at all if does engineering in addition, but discussions about that does not belong here. In other words, if Control theory is math, then we are interested in it because it is math, not because it applies to engineering.

Any med students here?
I started kickboxing recently and after my first class, i got punched quite a few times in the face.
Left with a mild headache, but it quickly went away after went home and relaxed.

My question is, am I doing irreversible damage to my brain by casually engaging in this sport? Am I making myself dumb by accident?

Photosynthesis takes simple molecules and uses light to create more complex molecules. Plants clearly produce negative entropy.

If you can't prove there is no loss of entropy in this reaction, the second law of thermodynamics is completely BTFO.

The ultimate redpill is when you realize Life on Earth is a cosmic attempt to fight back against the forces of entropy.

I need to find everyday products, structures, or items in general that have Engineering Design flaws. I am having trouble because everything in this day and age seems perfected. Realistically, if something had an Engineering Design flaw, then it's design would be obsolete by now, which makes finding something so much more difficult.

Any ideas would help greatly,

Universities have a design flaw. We do things backwards. We're essentially training people to become literate in a language, and to consume and eventually produce leading-edge research (ie papers). However most Universities (including mine) have zero mandatory exposure to any research paper during entire undergrad programs.

What exactly does quantum teleportation "teleport"? It sounds like you have to physically move the entangled pair of particles apart, which doesn't sound like teleportation to me. Is this just another popsci definition.

It lets you transfer the quantum state of one particle to another.
You start with two entangled particles, A and B. A is with you, and B is the target particle. Particle C is the one with the quantum state you want to transfer to B. You bring A and C together and perform a special kind of measurement on them called a Bell measurement. This puts A and C into one of several entangled states, and B ends up in one of a number of states which can include the target state, but may also be several different related states, which can easily be transformed to the target state. The Bell measurement of A and C tells you which of the possible entangled states you got. You communicate this to the person by B, and depending on the content of this message, they perform one of several transformations to the particle to change its quantum state to the target state.

If you look into the details more, you'll find that you can't teleport energy without that energy already being present in the initial entangled pair of A and C.

Gee I wonder why cosmic expansion doesn't break relativity inb4 not a particle. No that can't be the answer.
If two people stand on the moon and they shoot lasers opposite to each other, relative to you, an observer not looking at either will definitely appear to be moving away faster than light.

Maybe you're thinking of relative velocity? So if there is a satellite spinning around Earth(because that's how communication works because it's more practical because you don't always have a clear line of site to your target. So if a satellite shoots out two distinct particles moving at c then relative to you, an inertial observer will see FTL. Again you are confusing relative velocities.

yes, anon, you are right. Hagelin's views are unanimously viewed as laughable among serious physicists. however, the reason wikipedia says something that obscures this point is because wikipedia is run by a tower of subcultures who tend to self-reinforce their views, whether they be scientific, nonscientific, or completely ridiculous scientifically. i suspect the reason wikipedia says (said?) that hagelin's idea is "highly controversial among physicists" is because the wikipedians who pay attention to his article are a bunch of newage sciencelet cunts who fucking suck WAY worse than godfags.

Sometimes it takes time for an idea to truly ferment in your mind.

What is going on with the concept of gender right now in our society? I think it’s great that it’s being talked about more and people (hopefully) aren’t as discriminatory as in the past. At the same time, there is a weird phenomenon where science and biology are sort of being attacked or ignored.

For example, I’ve had people tell me that gender is completely a social concept, that it isn’t driven by biology, which is an absurd statement. I’ve also had people tell me there are no differences between male and female brains, which is of course not accurate.

Why is it so popular right now to downplay any biological differences between men and women, and attribute them to society? Is it because if you can find a biological basis between genders, then people are afraid that it gives power to stereotypes? Because it’s not the biological differences that reinforce stereotypes, it’s sexism itself.

Modern leftish philosophers tend to dismiss reason, science, objective reality and to insist that everything is culturally relative. It is true that one can ask serious questions about the foundations of scientific knowledge and about how, if at all, the concept of objective reality can be defined. But it is obvious that modern leftish philosophers are not simply cool-headed logicians systematically analyzing the foundations of knowledge. They are deeply involved emotionally in their attack on truth and reality. They attack these concepts because of their own psychological needs. For one thing, their attack is an outlet for hostility, and, to the extent that it is successful, it satisfies the drive for power. More importantly, the leftist hates science and rationality because they classify certain beliefs as true (i.e., successful, superior) and other beliefs as false (i.e., failed, inferior). The leftist’s feelings of inferiority run so deep that he cannot tolerate any classification of some things as successful or superior and other things as failed or inferior. This also underlies the rejection by many leftists of the concept of mental illness and of the utility of IQ tests. Leftists are antagonistic to genetic explanations of human abilities or behavior because such explanations tend to make some persons appear superior or inferior to others. Leftists prefer to give society the credit or blame for an individual’s ability or lack of it. Thus if a person is “inferior” it is not his fault, but society’s, because he has not been brought up properly.

It's not photographing souls, but yes, humans do have electromagnetic fields. Even plants do. What kirlian photography picks up isn't a ghost or your chakra or mana. It's the intersection of humidity, water content in tissue, ionization, gas discharge, pressure, voltage, and light surrounding all living things. The photos can be affected by everything from oils, sweat, electrolytes, water content, the surrounding atmosphere, pressure, and how well-grounded you are. Experiments debunk the hypothesis that they're evidence of a life force. Just electricity.
>>
The thing that gets me about Kirlian photography is that you can cut a portion off a leaf and sometimes the kirlian photo will show the entire leaf’s “energy field.” Wikipedia will tell you that it’s just water vapor left behind from when they picked the leaf up off the slide, cut it and put it back, but I’ve seen a video where they pick the leaf off the plant, cut it and then put it on the slide so the left-behind water vapor theory doesn’t hold water. Pun intended. Explain that shit, science.
>>
>>10499613
The cut dehydrates the surrounding tissue, just like cutting human skin. It also bleeds substances like moisture and various biological contaminants. Those have ionizing effects because the cells' contents have to be electric in order to function. Cutting a living thing is spilling water, fuel, electrolytes, and microscopic batteries onto a slide.
>>
>>10499636
>Cutting a living thing is spilling water, fuel, electrolytes, and microscopic batteries onto a slide.

Shit may be spilling out, but that part of the kirlian photo isn’t an outpouring of “vapor” consisting of water, fuel or electrolytes; that’s the fucking leaf.
