Besides burning stuff, what are some interesting things you can do with a powerful handheld laser like this one? This one even claims to be opensource. I've checked YouTube for some interesting projects people used this in but all I see are people burning matches and popping balloons.

Personal Question

What degrees do you consider useless and would you date someone who's majoring in one of them? I'm dating a girl who's majoring in economy and I'm about to freak out. She is a hardcore libertarianism, which I don't necessarily mind, but she keeps saying utter nonsense and when I show her historical/empirical evidence that disputes whatever the fuck she said, she goes "Everybody is entitled to their own opinion!!" Fuck economy. Also the whole of humanities.

I don't know if I can ask for homework help here, but seeing how must other places are retarded or refuse to help, I'll try here. A student attempts to identify an unknown compound by using chemical reactions to calculate mass relationships. After heating a sample weighing 0.4521g, the mass decreased to 0.3400g. When the product was reacted to form a chloride, the resulting mass was 0.3304g. a) Is this unkown a carbonate or hydrogen carbonate? and why? b)Given the answer to part a, the unknown is one of what two compouns? c)Write the overall balanced chemical equations for the reaction of each possible unkown with HCI.

Determined to post.

Dear /sci/ I do not believe cells have lipid membranes. I've posted here before and someone presented freeze fracturing as evidence of lipid membranes, because supposedly freeze fracturing allows one to see the lipid membrane directly. So I looked up freeze fracturing. The foundational papers on freeze fracturing don't prove the existence of the lipid membrane; they assume it. In the beginning of freeze fracturing, they were unsure what they were seeing, but they deduced it "must" be the lipid membrane, based on their assumption that such a structure exists. Later papers on freeze fracturing assume what they're seeing is the lipid membrane and cite earlier papers as justification. So freeze fracturing is not valid evidence of a lipid membrane. So I now ask: What other evidence do you have that demonstrates the existence of the lipid membrane? I have yet to be convinced. Here's some counter evidence: http://jp.physoc.org/content/280/1/105.short

Does life begin at conception? I don't care about abortion (probably support choice) but it seems pretty straightforward that as far as we can define "Life" conception is the only thing that marks a clear starting point for life

Can someone explain post scarcity to me? It is sort of science and business, so I figure it belongs here. Are we doing baby steps right now to get there? Like is the MP3 file a form of music post scarcity.

Why do you never hear about maths majors achieving anything outside of academia? Does their IQ not transfer in to the real world? Not a joke topic btw

>reading cognitive neuroscience notes on the underground >6/10 sits near me with her 1/10 hambeast friend >over hear them talking about how they could never get their heads down in school >continued ignoring their attention seeking Made me wonder what percent of the global population are scientifically literate? If they don't "get" science, or reject it out of hand, what world do they live in? They don't understand how a tree works, how the rain falls, or what planets are? What if they have had no education at all? Is my reality superior to those who have not reached my education and understanding of the reality in which we live.
