Trivia Flashcards
White gold is made of…
Gold & palladium (46)
Interesting property if palladium
Can absorb 900x it’s own volume of hydrogen
Jupiters 4 biggest main moons (Galilean ) moons
Io, Europa, Ganymede, Callisto
Unique features of Europa
Has lots of water, theorized ocean under ice could have life. On earth life could exist by subterranean volcanoes
What’s LENR
Low emiting nuclear reaction
Widom-Larsen theory
Wisdom Larsen theory
Low emitting nuclear reactions
LENR more plausible explanation for results of cold fusion experiment 1989 (pons & fleischmann)
How do car engines work?
Spark causes gasoline vapor & air in the cylinder to explode. Turbo uses rush of exhaust from exiting the engine to spin a turbine which drives a compressor that crams extra air into the cylinder extra air means more fuel burns
Longest neck of any animal who has ever lived
Elasmosaur, 76 vertebra neck, 39 foot long aquatic dinosaur
Earths magnetic poles are believed to switch every
200,000 years
Prinzmetal’s disease
Variant angina :sudden &severe spasm of the coronary artery, reversible & unprovoked
What is angina?
Chest pain caused by heart not getting enough oxygen
Hydrogen peroxide & & sulfur dioxide on planets is interesting because
Play vital roles in chemical reactions that form the foundation of life.
How can Europa possibly have life if surface is -260 degrees?
Elliptical orbit & Jupiter’s huge gravitational pull expand & contract europa’s core producing heat.
Titans surface (a Saturn moon)
Has an atmosphere & lakes of methane
Enceladus
A moon of Saturn, interesting bc has water on surface in form of vapor & polar ice caps. Geysers shoot water vapor out. It has an atmosphere
How can europa’s chaotic ice scape, Thera Macula, provide clues to how life could form there?
Heat from below melts a pocket above in the ice. The pressure causes the water to flow strangely. Ice above eventually caves in providing surface compounds like hydrogen peroxide & sulfur dioxide to warmer water in lake pocket below maybe forming ecosystems of microbes ??
Bright moon on Saturn
Enceladus bc it’s one big snowball, surface ice reflects light, it had an ocean of actual water by South Pole
Core of dwarf planets
Rocky, cool, no molten stuff
Highest mt in northamerica where is it?
Mt McKinley in Alaska
Largest network of caves
Mammoth caves in Kentucky
Who is Elizabeth loftus?
A psychologist, wrote the myth of repressed memory. Her studies show how easy it is to make people remember things that didn’t happen.
Bottom most layer of atmosphere
Troposphere where clouds are, 12 miles up, stratosphere is on top of that
Difficulty with wind as an energy source
We don’t fully understand how wind behaves. As a result, the system overloads & windmills break when wind gets too strong.
Windmills need to be made to be more adaptable to wind changes & we need to be able to better predict what the wind will do.
Ineffable means?
Beyond expression in words; unspeakable.
