If a piece of aluminium consists of 6.02*10^{23} atoms, how much does it weigh? How do we know Mercury is made of iron and nickel if we have never sent anything to visit it? What is the chemistry of iron? How do I count sigma and pi bonds and how do you determi...
In an atomic clock, the natural oscillations of atoms act like the pendulum in a grandfather clock. However, atomic clocks are far more precise than conventional clocks because atomic oscillations have a much higher frequency and are much more stable. There are many different types of atomic cloc...
We'll then have a mess of quarks -- the type of quarks called "up" and "down," which have certain masses and are the only kinds found in matter on Earth. Squishing even more, we'll stress the up and down quarks so much that some change their identities. Some will get a lot ...
And all geniuses have a very important aptitude in common -- they have an abundance of creative intelligence. Without it, they wouldn't be geniuses. They'd simply be exceptionally smart. How much creativity does it take to be a genius? We'll look at how imagination and productivity ...
As small as a nanometer is, it's still large compared to the atomic scale. An atom has a diameter of about 0.1 nm. An atom's nucleus is much smaller -- about 0.00001 nm. Atoms are the building blocks for all matter in our universe. You and everything around you are made of atoms...
(by learning new skills or solving puzzles, for example) boosts some cognitive ability, but these changes aren't permanent and do not have much effect on IQ scores.Another studyfound that exercise can increase the levels of brain-derived neurotrophic factor, a hormone necessary for new brain ...
Remember, all atoms vibrate to their own unique frequency. Imagine a couple whose atoms are perfectly in sync with each other. Even if you don’t believe in a higher power or religion, you have to admit that this feels harmonious.
For example, there have only been 1026 nanoseconds since the Big Bang. There are thought to be only 1075 atoms in the entire universe. When you consider that the Milky Way galaxy contains billions of suns, and there are billions of galaxies, you can see that that's a whole lot of ...
You can see that glucose is made of six carbon atoms (carbo...) and the elements of six water molecules (...hydrate). Glucose is asimple sugar, meaning that to our tongues it tastes sweet. There are other simple sugars that you have probably heard of. Fructose is the main sugar in ...
The nurse selects the nursing diagnosis of Risk for Impaired Skin Integrity related to immobility, dry skin, and surgical incision. Which of the following represents a properly stated outcome/goal? Th...
