/sci/ - Science & Math

Hey /sci/,

I'm a career chemist that has recently realized the necessity for higher-level mathematics. (AKA I've seen the light.)

That being said, I am currently taking a course in Ordinary Differential Equations. I have absolutely *no* background in linear algebra (matrix operations, bases, etc) and I need to get humpin' in order to succeed in the remainder of the course.

I have aggregated a number of resources, including from the sticky, but I am still having trouble organizing my studies and picking out the "most relevant" bits.

Can you offer me any advice? I would really appreciate it.

I've been writing trig functions in colored pencils and coming up with similar visual tricks to try and make my math notebook more interesting and personal. I like colorful things and seem to learn almost all visually, and people have really interesting--and varied--reactions to my rainbow notes.

I'd like to think interest and fun are directly correlated to success in whatever field, so I was wondering if you guys ever had any particular turning points where you suddenly found math more interesting (mostly because I need a motivational boost and want to think of more ways to make math seem less like a chore).

I found myself much more interested in computer science once I realized there were things like NP problems and started taking logic, and I started liking chemistry a lot more after synthesizing something. Still, I haven't yet broken the boredom barrier that prevents me from becoming a good mathematician.

You have 1 Liter saturated liquid water at 100 degrees C and add 4186 joules of energy. What is the final temprature?

Stranger 2: I don't know!

Stranger 1: it would still be 100 degrees c

Stranger 2: :O xD

Stranger 2 has disconnected

>Stranger 1 is probably in this thread

Hey /sci/, something I've been kind of wondering. The idea that if time travel were to occur, any changes would result in diverging timelines is widely accepted as fact

I was just curious if it was based on some larger theory, and if so could someone point me in the right direction, or if it just makes the most sense to the majority of people?

Brilliant! We'll get our best TEPCO engineer on the job immediately!

So how does /sci/ study? I enjoy all my classes, but I have a hard time actually sitting down and studying. I get easily distracted and end up fapping, browsing 4chon, or otherwise neglecting my studies.

I found out a way to answer my question in regards to calculating lumens!

"High Pressure Sodium (HPS) or Metal Halide (MH) lights can also be used. They come in 400w and 1000w sizes, and unless you have a large area to cover, the 400w is plenty. A 400w MH system costs about $200 and puts out as many lumens as 20 fluorescent bulbs. This fixture would provide enough light for an 8'x8' growing space"

How many lumens does a 400w metal halide lamp put out? Does anyone know? So if my grow space was ~6'x6' (Or less), how many lumens and/or 6500K CFLs would I need?

Why are you trying to synthesize MDMA dog? You are a dog, not a chemist. Give back my lab.
