I totally agree, but don't think that wikipedia-surfing is a good example, because you search for stuff that you want to know (or maybe easier to understand) while when reading a scrience book f.e. you have to read all the way through the article, even if some parts are harder to understand I tend to agree as well, but I've found that as someone who strives to learn almost to the exclusion of all else in my life, when that learning is severely depressed by any of a variety of factors, I'm encouraged to drink.
Maybe dumb people don't 'not care,' but they're just not as capable of learning, and lack to means of acquiring the necessary facilitation to expand their minds. Or, maybe you're right and they don't care. I think, as the years go on, I've come to believe that intelligence levels and opportunities are a lot more situational than I'd once thought. But yes, the desire, the motivation is a key factor in anything. The Excretory System - Human Body FREE Presentations in PowerPoint format, Free Interactives and Games.

Water, good ol' H2O, seems like a pretty simple substance to you and me.
But in reality, water - the foundation of life and most common of liquid - is really weird and scientists actually don't completely understand how water works. Here are 5 really weird things about water: 1. Hot Water Freezes Faster Than Cold Water Take two pails of water; fill one with hot water and the other one with cold water, and put them in the freezer. In 1963, a Tanzanian high-school student named Erasto B. Thankfully, Mpemba didn't back down - he convinced a physics professor to conduct an experiment which eventually confirmed his observations: in certain conditions, hot water indeed freezes before cold water*. Actually, Mpemba was in good company. But how do scientists explain this strange phenomenon? 2. Everybody knows that when you cool water to 0 °C (32 °F) it forms ice ... except that in some cases it doesn't! Note: Similarly, superheated water remains liquid even when heated past its boiling point. 3. 4.

The Rotary Piston Array Machine -- Air-Sea Temperature Difference Engine -- Solarthermal Power Generator The Rotary Stirling Engine The Wave Pump Heat Engine With No Compressor Portable Tent Platform The rotary piston array (RPA) is the possibly most compact and most elegant machine to transform the volumetric change of gas into shaft work and vice versa. It can be used as pneumatic motor, steam engine, gas compressor, vacuum pump and the like, but also as part of new heat or combustion engines which – like the Stirling engine – open new ways to harvest renewable energy.
Other possible uses are refrigeration and air-conditioning. The idea has been overlooked for at least 110 years, as some old patents indicate, and it seems to have been reinvented several times (e.g. The machine comprises an array of equally shaped twisted rotors with parallel axes.
