With teleportation as it's portrayed in Star Trek, would it kill the person being teleported, spawning a new complete person with the memories of the old? Or is the exact same consciousness moved? Does the teleporter kill you?

What would life be like on a Earth-like planet if it rotated on its X-axis?
Similar to Uranus, and more specifically, with the 84 year orbit (to increase chance of evolution), but still a 24 hour day.. Moons optional.
OP here, so this is how the orbit would look.. I'll upload more when I can.

I am going to defend my Master's thesis in a STEM field (Remote Sensing) in about a month.
Anyone got any advice they wish they had gotten this close to their defense?
Normally I know people would just ask their colleagues about this, but I was a huge anxiety-filled vagina until a month or two ago and subsequently did all my studies and work at home.
Go through it with someone who also know the field and try to anticipate questions they would ask
>>8261711
Just practice like a bazillion times. For my comps I recorded audio of myself giving my presentation and then listened to it all day while doing my lab work. It also helps to anticipate questions and just include the answers as part of your explanation to nip them in the bud. This will lead to the committee members asking fewer questions.
>>8261804
Interesting... so you had it mostly scripted out? I was largely planning on winging it, as I understand the material quite well, but this makes a lot more sense.
Also... How does one deal with a question to which they don't know the answer? Are you pretty much fucked if that happens? Anyone got any foolproof contingency plans?

Why are science people so fucking elitist?
I always see physics people shitting on chemists, who shit on biologists, who shit on psychologists/other social sciences etc.
Cant you faggots have an appreciation for all the fields?
Any smart person who's passionate in their field can do great things in their field. All of these fields are useful to society. Yes, even Psychology. No, most of the women/retards who do it are completely useless. But the truly smart ones will do better than your average ass, even if you do do physics.
People i see acting so fucking elitist are just man children who, ironically, i view as plebs, since they cannot see the value in the field they are deriding.

Would exposing someone to uranium or plutonium make people feel sick instantaneously like with superman and kryptonite?
>>8261161
how much?
>>8261161
no but plutonium feels a bit warm
No. Even with heavy exposure (eg roof of the Chernobyl reactor shoveling radioactive graphite) it would take a number of hours before you found yourself curled up into a ball puking up blood and convulsing somewhere.
Any good places to do online courses?
I guess thats a no then.

I am very fond of a friend, an historian, who independently discovered the algorithm to do multiplications by hand. Really, he had forgotten the trick after years of computers, calculators and first-digit approximations, and when at age 30 he found it, he urgently called me to ask if the method of decomposing 26354*336=((26354*3)*100)+((26354*3)*10)+(26354*6)*1 was known.

What's your opinion on our planets population?
Are we crowded?
Do we have room?
Whats up?
Room? Sure. Resources? Less sure.
I thought developed countries all seemed to have declining populations and only 3rd world shitholes contribute largely to overpopulation
>>8260786
>Are we crowded?
>Do we have room?
Those are the wrong questions. Here are some thoughts:
It makes no sense to talk about the world population as "we", because it has no coherent political agency. It is splintered into different nations, tribes, cultures, ideologies, down to the level of individuals, who don't get along very well. If we were the Borg, we'd be underpopulated. Since we're aggressive tribal humans, fewer may well be better.
The second question is how many resources you think everybody should have. I think it's ethically better if everyone has access to electricity, a fridge, warm water, enough food, transportation, even the occasional plane flight. I don't believe increasing the number of people is intrinsically a good thing. I don't even believe most lives are worth living. But there's a huge literature on population ethics, and it's quite complicated.
From a resource perspective, the key question is how labor and ideas can substitute for any specific resource running out, e.g. by inventing more efficient technologies, or by accessing previously unaccessable resources, or by inventing new uses for previously useless resources. And then there's the empirical questions how well these factors of labor and ideas scale with population. Do more people bring more to the table than they subtract? This is a function of their abilities as well as their behavior and interactions, so indirectly it's a function of culture and politics as well.
My personal conclusion is that any reduction of the world population is ethically good, and the ideal long-term goal should be something like 100 million hunter-gatherers spread over the planet with some remnants of modern technology of course. But this is rather radical and people obviously won't agree.
What do you guys think of IQ tests? I found one online, designed by Mensa to give an approximation of what you would score on their actual test. The questions only require you to recognize geometric patterns and stuff.
>http://test.mensa.no/
>>8260777
If a test concludes that a little cuckboi who decided to spend his time doing physics at a fast rate instead of enjoying life and taking it easy is smarter than me then that test is wrong.
Maybe we should measure NIQ. Where your NIQ is 300 mius your IQ and that way it would make a lot more sense.

AHAHAHAHAHAHA, MENSA is literally Scientology for "smart" people. Go ahead and take it to qualify for their paid membership.
Would there be less droughts in the world (like California) if we weren't bottling water and letting it sit in factories and on store shelves? It seems like more and more water is being packaged and less fresh water can be found in the wild. Faucet water is hit-or-miss. It seems to me as if we're walking into our own doomsday scenario by making all of the fresh water disappear, and what's worse is as most of our own fresh water we drink percepitates into the ocean and becomes salt water we are perpetually losing out on water that actually is drinkable. Does anybody else see this as a very frightening situation? Should bottled water be outlawed... and what do we do with those bottles in storage? Where do we dump the water?
Fuck off
>water disappears when you drink it

desalination is already cost effective, israel has the most effective disalination plant in the world I still dont know if they have a net gain from it tho its very hard to find it out if they broken even imo
also i dont think they share their construction plans any time soon which could also lead to a water crisis or tho technology is there already
Has anyone created a speculative map of the universe encompassing the estimated state of all known galaxies as they would be at this very moment? The current maps are all based on visible images. Some images are over fourteen billion light years old. But the average lifespan of a star is less than that. How do we know that shit's even still there?
Also, kind of unrelated but do you think that (if the universe is expanding) that being close to the event horizon would cause time dilation such that the actual age of object on the periphery is less than we would estimate by light year distances?

Actually, it's cosmology, but I'll give you a pass since you never completed the 9th grade.
>>8260498
maybe this:
https://in-the-sky.org/ngc3d.php?
I also wholeheartedly recommend SpaceEngine. It is free and serves as a speculative map. Known systems are in there as accurate as possible. Other stuff is procedurally generated using known parameters. looks great and at least fun to play around with.
I dont quite get your question, tho. What has the expanding of the universe to do with event horizons?

I have a master's degree in literature. After getting it, I realized it was stupid and decided to go back to school and set my sight on physics. But I couldn't do math because I fucked around during high school, so I decided to take all of the requisite classes first. Algebra and geometry I blazed through with little difficulty, but I'm in trigonometry now and MAYBE I'll get a B. Was my goal of physics just too high?
>>8260489
Physics in what capacity?
Do you want to do PhD level research, be a technician, be a scientific writer?
For a physics degree you'll need at least Calculus 1 to even begin taking introductory classes. Math can be learned by anyone, hard work is the element that matters most.
You can do it!!
>>8260492
OP here. In my ideal world, I'd like to be an astronomy researcher. I love reading about stuff like exoplanets and such. I'm aware there isn't that much of a need for such people, though, so probably I would more practically look for a university job teaching. In truth, I could teach English right now, but i have no desire to teach low level English courses to just-out-of-high school students.
I guess I'm mostly concerned because my friend said I'm too old (28) to learn a complicated science and I went back anyway, and this class, which isn't even as hard as physics will be, is borderline stumping me.
>>8260502
It almost sounds like you would enjoy being a scientific writer. You are certainly not too old to learn a complicated science, but it will be tough and require a lot of hard work. Luckily most astronomy is not overwhelming complicated in the math department, but there is still a lot for you to learn between trig and what is needed for astro.
Hey guys, newfag here. Im starting an intro to comp sci course here in a couple weeks. Im really nervous. It is focused on java and object oriented programming. Anything i should be doing now to get ready? Also, anyone have a digital copy of Big Java: Early Objects (6th ed)? shits expensive. Thanks for the help guys!!
>>8260443
>It is focused on java
Drop the course.
>>8260443
Just pirate it.
