Curved Space

I haven't written one of these for quite a while, so it's high time I did. In italic are lambdapi's questions, somewhat paraphrased for brevity.

Light and GravityCollapse )

Biology, eh?

Those of you who know me in real life are probably aware of my general disdain for biology. Now I'm not about to change my stance at all - obviously physics will forever remain far superior - but having been researching and pondering biology for a story I'm currently writing, I've come to realise exactly why I disdain it so.

Rant - not all that offencive to biology, actuallyCollapse )

PS forgive any typos or complete inability to spell; I haven't slept much the past few weeks and I am barely managing to keep my eyes open to finish typing this.

Hal Spacejock Support Crew

Great books! You should all read them!

Seriously, if you can, get your hands on Hal Spacejock. There's not much comic SF out there, and certainly very little written recently. Worth the postage for those of you living elsewhere.



I joined Hal Spacejock's Support Crew
I didn't pay anything,
I didn't sign anything,
and I didn't read the fine print.
Just like Hal!


No space pilot can exist in a vacuum (hah!), and behind every successful pilot there's a talented and dedicated support crew.
Hal Spacejock is one of the least successful space pilots in the history of the galaxy, and a worldwide support crew is needed just to get him off the ground.

Light - Momentum and Energy

Someone asked this question on my last/first sciencey post. I decided that it was too long an answer to just leave in the comments, so here it is, question and answer:

Question: What happens to light (a photon) as it passes through a transparent medium? We know that photons do not have a mass, however they do have energy and momentum. If we consider the equation: E = m c^2 / sqrt(1 - v^2/c^2), a massless particle, must always move at the speed of light (in a vacuum), c [E = 0/0]. But what happens when light passes from a vacuum into air, or from air into glass? Does the photon slow down, causing the bending of light? And if so, what happens to its energy (as E would equal zero if the velocity were anything but c)?

AnswerCollapse )

I love science

I enjoy explaining things to people, it's just one of those things about me. Especially if said things pertain to science, as I also enjoy science. So I am going to rant write about science on my eljay. Because I can.

This is meant to be accessible to people who haven't been scientifically trained, so no (or minimal, at worst) maths where possible, unless someone specifically asks.

In searching for a topic for this first scientific rant discussion, I asked a friend, lambdapi, what questions relating to physics, chemistry or maths he had that he would like an answer to. After much misunderstanding, he wanted to know the following:

How things can become "infintely heavy" as they reach the speed of light. How things require an "infinite" amount of energy to get to absolute zero. How the hell a point with nil size and infinite density can have a definable mass.

Before I go to my answer, I'd just like to add a disclaimer. In most cases (and certainly this one) I'll be working entirely from memory, which means I won't have anything specific to cite. I'm not plagiarising; I'm making it up as I go along. If (gods forbid) I get something wrong, feel free to correct me, but please, be nice about it. I tried.

One final thing, if you have any questions, or if I leave something out, feel free to ask in a comment. I'll try to answer, though it may not be until a future entry.

And with that, faithful (or bored) readers:

Infinite Values in Physical Concepts


how things can become "infinitely heavy" as they reach the speed of lightCollapse )

It looks like I've run out of time for the rest of the questions. I'll do them later and add them in (and forward date for your friend list spamming pleasure). Any questions on what I've covered so far are most welcome.
If a computer crashes in the woods, would anyone hear it fall?

Entry the Zeroth

You have reached the livejournal of Abygael. We hope you enjoy your stay.

This entry has been designed to provide a less obnoxious alternative to our earlier friends only announcement.

This journal will be concerned with a wide variety of issues, stories and recounts. In all likelihood, on common trend will remain for very long. It is all subject to my whims and bouts of boredom.

If anyone wishes to be able to see protected entries, they need only to comment briefly explaining who they are and they will probably be added.
