Supervisor for Apple. Could be confused as babysitter, frat-house mom, or cat-herder depending on the day.

Engineering is mostly in Cupertino.

You're not my supervisor! Though I do think that babysitter should be in your job title officially.

I'm a (semi) retired engineer. I'm now teaching (warping) young minds teaching them engineering (www.pltw.org).

You think managing adults is fun, try the same thing with really smart, but no common sense teenagers :wave:.

I have a question for you. When I was taking physics in high school, my teacher had a standard problem: you have a vat of water at 65 degrees, and into that vat you add an iron ball of some weight and temperature, a block of ice at some weight and temperature, as well as other othings and I calculated the resultant temperature of the water. Do you know the type of problem I am talking about and how to solve it?

Yes I do! :wave: My students are working on the exact same types of problems at the moment.

As I remember, it was fairly difficult to raise the temp on a significant amount of water - even 100 gallons or so. Adding a few gallons (10 or 15) of water at 15 or 20 degrees lower than the original temperature would hardly affect it all. Am I remembering this correctly? It has been 4 decades plus since HS Physics.

I am a graduate student at UT in chemistry. I worked for a while and saved some of my gear from my old set ups that I am using on my current 80L aquarium. I always make careful purchases and when I don't need anything I sell it online or trade it. I buy all of my filtration and media I can't make myself in bulk and I make all of my own supplements. I make many of my fish foods as well. I simply have a smaller aquarium for my smaller budget and I get to enjoy the challenge of keeping a smaller tank.

Did they have physics back then? laugh.gif

Sure we did. But we used slide rules. I was a reel geek with a circular one that clipped onto my belt. We also thought the sun revolved around the earth and the world was flat.

And you couldn't tell that by looking at me? I thought the white hair and beard were a dead giveaway. Ooops. I shouldn't use the word dead.

Ya, water has a fairly unique property in that it takes quite a bit of energy to raise or lower its temperature, hence cold lake water in April, warm lake water in November. :D

I do Paintless Dent Repair for money, and photography for fun. I make just about enough doing weddings and portraits to keep me in working equipment.

Offroadodge we need to talk. We were just talking today about coming to see you guys. Charlie Mills works with us and I think he is friends with the owner or manager there. Our company name is Texas Dent Works.
