Can you diffract a human? Since Plank’s constant is on the order of 10-34, the de Broglie wavelength is virtually undetectable for large amounts of matter. There is much evidence of matter possessing such a de Broglie wavelength. Well, theoretically, since all matter possess wave-like properties, so do humans, and cats, and whatever you please. […]

Can you use the quadratic formula for inequalities?
Can you use the quadratic formula for inequalities? In other words, a quadratic inequality is in standard form when the inequality is set to 0. Just like in a quadratic equation, the degree of the polynomial expression is two. This method of solving quadratic inequalities only works if the quadratic factors. What is the purpose […]
Why do pennies sink in water?
Why do pennies sink in water? The reason the pennies sink in water is because of an idea called density. The pennies have more density than the water, and so the pennies sink. Anything with more density than water will sink in water, but other objects that have less density than water will float. What […]

What planet spins the fastest?
What planet spins the fastest? Jupiter What determines how fast a planet spins? The rotational speed is normally determined by the initial angular momentum when the planet formed, but may also be altered subsequently by large collisions (as for example the collision of the earth with another planet which gave us our moon). Why Jupiter […]
