A collection of thoughts and asides about life. And if I think of anything that needs to be mocked, it will show up here.
"If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence. The origin of myths is explained in this way."
--Bertrand Russell
Daniel Stroh1 posted a great article about building a solar heater for his garage. Stacking 50 soda cans painted black, he was able to increase the air temperature by 15 degrees from input to output. Daniel remembers that his father had built something similar that generated a 110° difference between incoming air and outgoing air.
This is a great idea!
