Anyone here doing a CS major, good at computers but bad at Physics and Chemistry? My basics are not that good and I feel like Physics and Chemistry are eating my GPA.

Is intelligence contextual? Could someone be intelligent in one aspect but dumb in another? If the answer is yes, where does IQ come into play?

If you started studying aerospace engineering right now you could potentially be the first person to set foot on mars. Given the previous career trajectory of astronauts and the average age of a 4chan user it's a pretty good bet that the person who does set foot on mars will be within born within 2-3 years of you. All you need is your aero degree post grad and doctorate and 20/20 vision and you're set. How does that make you feel?

Sup /sci/ I'm confused on when to use the "ac method". I understand I have to have: (ax^2) + (bx) + (c) for it to work. But this problem in the picture doesn't seem to work... or am I retarded? All help is appreciated. When I submit the answer it says it can be factored more.

Can anyone explain how this works exactly? Because to me it would seem it would use even more power.

Hey /sci/, non-physicist here. I was wondering whether it's possible for a natural satellite to have moons/a ring system of its own, or are there forces that would prevent that?

>in the mirror I look like a 7/10 >in a random mirror in the street I look like a 4/10 >in pictures that I take I look like a 5/10 >in pictures people take I look like a 2/10 I've looked around and I discovered that the familiarity I have with my face hides all the asymmetries presented in it. source:http://www.ncbi.nlm.nih.gov/pubmed/15178167 Ok so what I want to know is: how can I have a proper idea of how people that recently met me see me? Can I trust photographs or videos of myself to know this? [spoiler] I know this is a shitty thread, I'm just really curious.[/spoiler]

If we had two perfectly identical truly isolated systems, would they perform identically? I've heard that there are random things out there and this would prove otherwise, but people only seem to assert that things are random without really proving it. I've also seen the argument that things which we call random, such as radioactive decay, is only apparently random because it is impossible predict it, but that it's not actually random. I'm confused, /sci/.
