The effect of screens on the brain and body?
Do we know much about the "frequencies" running through the body and how they're altered by screens?
When I wake up and use a screen, be it TV, monitor, phone, versus waking up and going outside, I notice a significant difference in my experience. I can't quite express what it is, but it doesn't feel good at all.
Does science have anything to say about this?

Is there going to be any interesting breakthrough in next 100 years that will provide new sort of outlook on life?

It seems currently everything is just progressing on what's already been known for past 50 years and little by little small optimizations that make things go faster/cleaner are happening, but nothing major. Nothing so out of imagination that would transcend current knowledge.

Give me your best outlook to what's to come

nope. which do you think is easier, fixing a habitable planet or making an Mars habitable? Keep in mind Mars has no magnetic field to trap gasses if you wanted to terrarform.

>1.00000000000000000....0001
can't represent an infinite string of zeros, because the string clearly ends in a one.

The only representation that makes sense is for "...." to represent an arbitrarily long, finite string of zeros. So the difference between the string in question and the number 1 is an arbitrarily long, finite string of zeros that ends in a one: 0.00000000000000000....0001

>> No.12267567

>>12267393
The thing is, that technically only only one of those 3 numbers exists.
0.999...999 is either finite, or is still missing a few 9s at the end.
Same with 1.000...001.
How much is 0/1? Because that's the difference between those 3 numbers.

Define "time travel". Einsteins theories show that time is not continuous, and that certain objects can travel in time at different rates relative to eachother depending on their gravitational pull as well as their velocity.While we have no way to move backwards in time, we know that time dilates as we approach the speed of light, so moving forward in time is certainly possible.

>> No.12267534

>>12267527
different rates =/= not continuous

Brainlet cross-boarder here, explain this to me in workin' mans words.

Wouldn't efficient teleportation violate the first law of thermodynamics because of potential energy? If gravitational potential energy is mgh then to not violate this law the teleportation process would have to, er, expend equal to or greater than the gain in potential energy if teleporting it upwards? Else if the energy used in teleporting is less than the gain you've created energy?

>> No.12267428

>>12267228
I wouldn't say that is much of a problem regarding the first law since you could just input energy to reach that height (assuming what is meant is that the person is atomised and then reassembled). A bigger problem would be the second law in that entropy tending to go up means the teleportee tends to go incorrectly assembled and dead.

Grades mean fuck-all in the real world, the only place they have any bearing (beyond whether you passed or failed) is OTHER educational institutions. But even then, grades would simply make entrance easier and not instantly delete any possibility of success in that route. Same applies to the reputation of a school. Exception goes to schools that give out fake documents like how in the Middle East there are shitloads of places that you can simply buy a degree from to the point where there are more people with a fake degree in the Middle East than with a real one.
