Hi, I know you posted this a while ago but I am about to begin my degree for space studies with focus of Aerospace Science and since they’re somewhat similar (obviously yours probably much harder) just wondering if you have any tips to do well. I’ve been doing some prep by watching videos like this since I know my first two courses are Intro to Orbital Mechanics and then followed by rocket propulsion
@Canthev Жыл бұрын
@@Chronicl3x you'll do great. It'll probably be hard but you clearly seem to have an interest in the field and passion for the knowledge will be the biggest asset you have to make graduating easier. The coursework I went through was pretty hard and there were LOTS of classes. What made it bearable is that I was genuinely interested in what I was learning. If you go into the classes really trying to genuinely understand the material, it will be MUCH easier than if you go into the classes just trying to get the grade you're looking for. If you find that the coursework isn't as cool as you thought, there's no shame in switching majors / degrees. Most of the coursework builds on earlier coursework so if you don't like the early stuff you probably won't like the rest of it. And again, striving to have a great understanding of the early coursework will make the later coursework much easier. You got this :)

Orbital rendezvous was made possible by Buzz Aldrin. He understood the physics behind it. He wrote his doctoral thesis on it. Early on in the Gemini program, they tried to rendezvous with the Titan-II second stage booster, but failed. They would do a burn to add velocity and found themselves getting farther away from the booster! They didn't realize that by adding energy to the orbit that the semi-major axis INCREASED and they went higher and actually slowed down with respect to the booster. Aldrin calculated that you have to decrease the orbital energy, drop into a LOWER orbit, then you travel faster than a higher orbit object! Then once you are almost under it, you add energy back to raise your orbit to the booster's orbit and then rendezvous!!! This was one of two major things that Aldrin contributed to the space program that got us to the moon. The other was putting a capsule under water and showing everyone how to work in zero G!

Always having an interest in astronomy back in 1979 the forthcoming appearance of Haley's comet was of was of great interest to me. How to know where to look? I bought an Apple II computer, learned celestial mechanics, learned programing and began plotting positions. The comet elements of orbit allow one to calculate the position of the comet in heliocentric ecliptic coordinates, meaningless to an Earth observer. So translate to geocentric ecliptic coordinates, not much help. Next translate to geocentric equatorial coordinates. As across check on the program I calculated a problem using the program then with a hand held scientific calculator and wrote down each step and result. Agreed very well but that was 12 pages of calculations. Little did I know that by the time of arrival there would be how to locate the comet charts everywhere. But wow the learning was worth it.

more mass --> more force, but also more inertia --> same acceleration.

@@jimswenson9991 If the force or gravity between 2 objects is dependant on their mass you can't say they accelerate toward each other independant of mass.

@@blackmancer This is because as the mass gets larger, the inertia also gets larger. Inertia is "holding back" the object, while the bigger mass, is trying to bring the object closer, faster. These 2 cancel each other out. Some will take offense, but his explanation was good

Yes, it's a tricky point you've noticed. Hopefully I can explain. In the general case, yes, objects with greater mass attract each other with greater force. Therefore, two Earth-mass objects a million miles apart will attract each other much faster than two car-mass objects a million miles apart. But the specific case of two objects with different mass falling at the same rate only holds when those two objects are *hugely less massive* than the object they're falling towards. If you have a one pound cannon ball and a two pound cannon ball and drop them at the same time from the same height, they appear to hit the ground at the same time. However, in reality, each cannon ball is attracting the Earth to it as well. Do the maths, and you'll find the two pound cannon ball will actually hit the ground before the one pound cannon ball. But the difference between the two is tiny, because the pull of the two pound cannon ball on the Earth is only minutely larger than the pull of the one pound cannon ball. I calculated that the two pound ball would fall something like 0.00000000000000000001% faster. So yes, it falls faster, but at these sorts of scales it simply isn't measurable, so it's rational to say two objects fall at the same rate. In a way it's like the experiment where a device drops a ball bearing while expelling a second ball bearing sideways, and the two ball bearings hit the ground at the same time. For all practical purposes, yes, they hit the ground at the same time, but in theory the ball bearing shot out sideways will take a microscopic amount of time longer to hit the ground because it has travelled part of the way around the Earth's curvature.

Actually, Newton's Second Law in its complete form looks like this: F = V(dm/dt) + m(dV/dt). F = ma is a simplified form for a constant mass which is not the case for a space rocket.

LukeRM It's not that big of a deal, and scientific progress is in this age is influenced predominantly by international efforts, with some countries affording to contribute more than others. As for the American mathematical and scientific communities, they use (and have long since used) the metric system for the most part, but often communicate to the public using the Imperial system because that is the system that most in the general American public are familiar with. Anyone who is comfortable with math or uses it on a regular basis already knows that the metric system is far easier and precise to use than the Imperial system. You don't have to be a resident of any particular nation or aligned to any particular political party to know that.

Jim Panse "Teaching" any aspect of religion, especially creationism, in any secular school system should be strictly outlawed. If a person wants to scare themselves into believing in deities, magic, and angels, that's their own personal business. It should be considered a crime for that sort of stupidity being introduced as curriculum in an educational institution.

Treetop64 That's the thing, it isn't like the two are pretty much equivalent and each side of the atlantic just choses one for cultural reasons, metric is fundamentally a better system. As an Engineering student studying in London whenever we have to unnecessarily expend the extra effort of using imperial units because of some regulations that were written in the US, I wonder why the hell cutting edge engineers don't all switch to metric and make their lives easier and their work more easily compatible with the rest of the world.

Ricky Bugatti Kerbal Space Program. A realistic space flight simulator. You make a rocket or a plane out of stock parts (you can add shit ton of other parts with mods), and fly your vessel to desired destination (moons, planets, asteroids etc), build space stations, colonies etc. All of it using realistic newtonian physics and orbital mechanics. You can make the game even harder with mods such as Real Solar System, Life support, real life parts. Also, exploding rockets into the ground and watching Kerbals freak out while they fly in all directions is pretty good stuff.

It was not Aristotle who proved the roundness of the earth but a much earlier philosopher…. I can’t recall his name right now. He even measured the radius based on the difference between the shadow of a stick between some place in Egypt (closer to the equator) and in in Greece during the summer solstice, after noticing that on that date there was no shadow cast inside a well.
