I've been investigating photography a little but am confused on how lenses, and focal lengths, really work. This question has been with me since I was a little kid playing with magnifying glasses, actually. So, many pictures show light entering a lens as straight lines: But if only light rays parallel to the lens could enter, you would only be able to see an area equal to that of the lens, right? Since you can see the entire sun, and not just a lens-sized portion of it (pictured), through a magnifying glass, this type of diagram must be incorrect. Other images (below) show straight lines through the lens, which kinda confuses me; don't lenses specifically bend light? And what are the lenses in these pictures supposed to be doing? So, what exactly is a lens doing, and where are the light rays coming from, how are they being manipulated, and how are they ended up?

"SR-71, half off!" Also, this thing looks reasonably cool... ... It's called the NASA Mini-sniffer.

Dont think so. The less imagination you have the more kits you buy ¯\_(ツ)_/¯

I made panettone and am making ciabatta bread for Christmas. Panettone is a labor of love if there ever was one- I even thought I broke our stand mixer and pored through the dough looking for a tiny piece of plastic. To have it for breakfast, you have to start it the day before and wake up at like 5 AM. It was intense. Now I'm making the ciabatta. It is SO MUCH EASIER. Ahhhhhh....... -

i just made one of the most stupid mistakes of my life, up there with writing calculator syntax on ap calc despite being explicitly told not to. i procrastinated my final assignment till it was due in an hour (i had a first draft so i thought the changes would be small) but i couldnt finish it till 00:15 (it was due at midnight) and now it looks like i might get a c. do you think the professor will have mercy? holy **** i am such a numskull

My team's robot completely crapped out... the night before competition. "Anything that can go wrong will go wrong, and at the worst possible time". Thankfully, we fixed it just in time with some Boy Scout torture. (The robot uses lots of string and knots, which Boy Scouts are great at). Here's hoping the fixes will work through comp. -
For the good of all of us except the ones who are dead...

My team's robot has blood on it, so now we can say it's made with blood, sweat, and tears. Nobody was hurt, I just got a small cut, but it's fun to tell people our robot has blood on it. -
start one and show off to the college admissions people >:)
