Hello anons.

I've recently been taking some physics classes and realized I like it WAY more than CS. Problem is, I'll be done with CS in 1,5 years.

Is it worth it to study another 2/3 years for physics. I'll be 28 when I'm done, but I'm scared that it'll fuck with me in industry.

What do you fegs say? Just do CS and fuck college or go physics and CS and enjoy my time? My life of gym -> study -> time off is pretty kino atm. Wouldn't mind doing this for another year.

Have any of you been a part of a research team before? What were your experiences?

First time being invited out to a research team station. La Selva most likely, either way it'll be down in Costa Rica or Panama.
Talking to one of the alumni that went there before, as they're very selective:
Is there cult shit that goes on here?

Other than that, it looks fun and informative. But there's a lot of rumors that I've heard about some of the SA facilities and staff members. Anyone else have a 'normal' experience going to one of these? Because I'm supposed to go to become initiated into being a 'real scientist' (to quote the alumni) like everyone who goes there.
Thoughts?

It's a harder sell for a pop boy like me, I can visualize a particle, it's like a marble and it's made of smaller marbles, but I don't understand what a field is really, like how do I visualize a field non-mathematically and incorporate it into a translatable world picture/what are these fields made of?

>it's like a marble and it's made of smaller marbles

Yeah when I was younger that was how I thought as well, but the more you learn about how reality actually operate on a fundamental level
the more you realize that that notion isn't compatible with how reality really works once you look under the hood and pay attention.
You come to realize the thing that's actually real was these fields all along.

As for visualization I think about them as locations in space that has properties that are diffused thru-out the area they occupy.
On a human scale the closest you can prob get to convince yourself it is actually real in a visceral way is playing with magnets.
You can clearly feel that the field is there and just how absolutely real it is.

you then realize that when you put your hand up against a surface and press you never actually touch anything, what you feel are all the tiny fields that make up your hand
press against the tiny fields that make up the things you touch. When you realize this truth you can start accepting how reality
is a lot more like them magnets attracting and repelling one another than anything like our everyday notion of solid objects colliding.

I get it up to the point where the question of what the fields are is. I get the math works but I don't understand what these fields are made of if it isn't stuff that ultimately would qualify as stuff and not just potential stuff.

Consider an alien that follows a very odd body plan. This here is what I will call a sky watcher. It is a very long lived creature, with a telescope on its "back" that points to the stars. It is not capable of communicating with others of its species. Would it be possible for this thing to come up with grand theorys of the universe all by its self? So it is intelligent, just not capable of using that knowledge for much

Hey i was doing calendar calculations for years very far into the future using the following algorithm

day/mod7

jan 0 feb 3 march 3 april 6 march 1 june 4 july 6 aug 2 Sep 5 Oct 0 Nov 3 Dev 5

For first two numbers of the year mod 4, substract result from 3 and multiply by 2

last two digits divide by 4, disregard decimals, add result to original last two digits, do mod7 on result

now add all results and do another mod7

now 0 is sunday 1 monday etc

i figured that the length of the year doesnt really matter because lets say you do year 5648465, you only have to do mod4 on 84, because you are only caring about the remaining rest.

now i was using this http://7is7.com/otto/weekday.html calculator to verify my results. it confirmed that the 1.1.2000 is a saturday and so is the 1.1.20000 the 1.1.200000 etc up to the first january of the year 200 trillion which is a monday....

have i missed something or is the software wrong.... its the only software i found that does these very big dates

>> No.14503294

I don't follow your description of your algorithm, but the length of the solar day is slowly increasing, so the number of solar days per tropical is decreasing. If I reckon correctly, by 13,000,000 AD, the year will be about 364 days long. Certainly by 200 trillion any calendar calculation will be in error.

>> No.14503329

>>14503294
But, ignoring details of the Earth's rotation and orbit, and of the Sun's timeline for expanding into a red giant, the Gregorian calendar has a 400 year cycle. So if you only work with the year modulo 400, you should be able to generate the days and dates.

>> No.14503342

>>14503329
Probably the online calculator has an overflow somewhere in the conversion from the input year to the year modulo 400. Most use cases for such software don't go beyond 2100.

In order for an alien species to reach the same technological level as humans would they need to look similar to us? limbs to manipulate the environment and tools, an expressive face or equivalent in order to form social groups, eyes and ears or equivalent to experience the world.

Are there any experiments that I can do to prove that humans have been to the Moon? I'm not skeptical of it, I think there's plenty of photo/video evidence, but I'm just very curious.
I know some of the Apollo missions left some laser reflectors to measure distance. I have access to some pretty powerful lasers. I would need to check exact specs of these lasers, but how feasible would it be to try to hit one of those and measure it back? What kind of equipment would I need?
Other than the lasers, are there any other experiments I could do?

This idea isn't really wild or even new. The concept that we should focus on solving the problems on the planet right in front of us rather than trying to escape them or move on from them is as old as our first forays into space (lest we may simply bring these problems with us to the stars). Even outside of educated circles.
It's been tried for years, but ultimately we're not much closer to solving our problems here on Earth as we were a few decades ago.
