    In university lectures, what note-taking software do you use?

    Hi For keeping with full disclosure - I hope to use this information to determine the need for an idea I've had that would make the lives of maths/physics students easier. I have just two questions I hope you can answer... What software do you use for taking notes during lectures and...

    Science/Physics related app idea

    Actually - the orders of magnitude app will be so simple. In fact it would be too simple for the type of project I'm doing. Something with the future of the Universe thing will be great but can't think of what exactly would make a good app out of that.

    Ah, Thank you Dennis. I really appreciate that. :)

    Science/Physics related app idea

    What I like in Science/Physics is the cool stuff. How you can travel in time by moving at fast speeds, the bigness of everything out there and the future of the Universe. I'm usually not interested in abstract things like developing a gravity simulator - my understanding of physics is that...

    Science/Physics related app idea

    I'm looking for one. Something that would be useful and fun to develop at the same time. What would you like for a physics related app?

    Dark Matter or just New Space?

    Hi I rarely have a background in physics (yet!) But based on my popular knowledge I understand that the Universe is 'expanding' in a loose sense of the word - which basically equates to the fact new space is being created all the time which in turn resembles a Universe where the distances...

    Universe expansion faster than light?

    The speed of light is a constant. Yet the Universe's expansion seems to be getting faster and faster. So my question is, when the speed of the expansion of the Universe reaches C the speed of light, what happens. Does it remain at that speed? Does it exceed it? Or does it slow down?

    Energy required to reach Escape Velocity

    I think I know the things you're referring to, I'll say them again... "It's impossible for one individual to carry out a project like this on a limited budget" I don't think it's impossible, and if I later find out that there's a part of it which is impossible without a multi-million dollar...

    Energy required to reach Escape Velocity

    I will explore the links you've given in detail, and thank you very much for it. One more point, I'm not in the US, in the UK actually. And from what I hear laws forbidding things like this aren't as strict. I believe I can do this as impossible as it sounds. Who knows, as undoubtable as it...

    Energy required to reach Escape Velocity

    Oh my goodness. I'm willing to put in the work, but to work on a hopeless endeavour for months without knowing it's not going anywhere would be silly. The answer to my question will help me understand the feasibility. Also, yes we can assume the fuel is weightless. I'm not planning to launch...

    Energy required to reach Escape Velocity

    I absolutely get that the rocket needs to be designed which is why I'm looking for a total and complete approximation. A small rocket but let's say the whole thing payload + the rocket's materials weigh 50kg. Let's ASSUME for now the fuel will be weightless and adding it to the rocket will not...

    CS career choice

    That is sort of my aim. I want my career to be something other than abstract code for people's websites and software. Being a robotocist allows for innovation and what is built does use the software side of it a little bit to program the robot, but it is a physical manifestation rather than...

    CS career choice

    What careers can a computer science graduate get into other than the obvious software/ web development? Are there any careers with less computer work and more human interaction lol, and a more mixed workforce. From experience, workplaces in this field are hugely dominated by men to the...

    Energy required to reach Escape Velocity

    Thanks, yeah, I was meaning to look into the Tsiolkovsky rocket equation but got sidetracked by some other replies in that thread. From a brief look into it - looks like it will take a lot of work for me to be able to fully 'get' these equations. I'm sure it can all be put into actual...

    Energy required to reach Escape Velocity

    Interesting use of the word 'simple' there lol. I'm not that great with equations, is there a more English-friendly source?

    Energy required to reach Escape Velocity

    Can anyone help me work out the energy required for a rocket powered craft to reach escape velocity. What I'm looking to find is the amount of fuel (in any measurement) that will need to be burned simultaneously to achieve this for a craft carrying a payload of 5 to 10kg. Any help/links to...

    Launching an object into OUTER space

    About earth's Escape Velocity; the place I have the problem is when I jump, I'm clearly not travelling at 11.2km/s and yet I'm escaping the Earth's gravity - although very slowly and for an extremely short time. When a rocket is 20km above ground the escape velocity should be less since it's...

    Launching an object into OUTER space

    That is extremely interesting. So one could, if one was very rich of course, select a route and 'fire' the spacecraft towards it. If the route is selected carefully enough the object in its millions of years of travel make its way past thousands of stars. Possibly to be intercepted by an alien...

    Rocket from troposphere - Why not?

    Why aren't helium balloons used to carry rockets or payloads to the troposphere which is about 25km above sea level before they are launched? To reach actual outer space is 100km above sea level. The above will in turn save 25km worth of fuel and the overall mass of the rocket which needs to...

    Launching an object into OUTER space

    Yes, solar panels. For the type of data gathering I aim to do, it will use need extremely little electrical energy. Possibly that used to charge a mobile phone. Let's keep this hypothetical. I have two more questions. 1. In space if someone pushes an object, on earth friction causes...

    Launching an object into OUTER space

    @russ_waters 1. I recently joined the forum so forgive me for not knowing which is the 'serious' place to post a thread. 2. I understand and admitted it was a very ambitious goal, impossible is a word I don't like to use unless it's completely beyond the realms of possibility. But it's...

    Launching an object into OUTER space

    Woah I didn't know this. The fastest travelling plane can only travel at half that speed. So to make a rocket pointing straight up - that would require a huge amount of fuel. This is a good article I've found that I'm currently reading...

    Launching an object into OUTER space

    Is that a revelation to you? I mentioned in my original post that I don't understand the challenges involved hence asking. It's a pretty simple concept actually, when you don't understand something you ask. The other side of it is when you don't know the answer, don't try to ridicule the asker.

    Degree - Career relationship

    By job I mean something which yields money. I'm absolutely fine with research, in fact I find it quite interesting an enjoyable. How can someone get into one of these research-jobs.

    Degree - Career relationship

    Hi, I'm an about to be CS graduate but my interest in physics greatly outweighs that of programming or developing software. Especially theoretical physics or anything related to physics for that matter so what I'd like to do is to go into a physics job however not having a physics degree I...
