Others simply make an occasional involuntary typo.
Here is your chance to learn a little science. Asteroids orbit the Sun as planet-like bodies ranging in size from a few hundred meters to a few hundred kilometers. The difference between a planet and an asteroid is a question of size. Multiplication in biology means reproduction, which is microscopically accomplished by cell division.
Several plays on words: A lepton is a particle not participating in the strong nuclear force such as an electron or neutrino ; in the sentence, "lepton" should be read as "leapt on".
An "ion" is a charged atom or molecule; in the sentence, "ion" should be read as "eye on". A buckyball is a soccer-like molecule of carbon atoms.
Gneiss is a type of metamorphics rock characterized by alternating dark and light colored bands. Sedimentary rocks are derived from deposits of sand and grains.
Newton's first law states that a body in motion remains in motion and a body at rest remains at rest unless acted upon by an unbalanced force. Dew appears on plants because air cannot contain all its water vapor at cooler temperatures. The Moon orbits the Earth because of gravity.
The taxi driver confused the words "magnets" and "maggots". Of course, if there were no Sun there would be no light during day and night. There are lots of play on words in this title: Integration can mean the merging of two distinct disciplines in this case physics and biology or the mathematical process of finding the area under a curve, which is often performed in physics calculations.
Epidermal cells are skin cells, which make use of sunlight for various biochemical processes. It is clever to refer to skin as a solar cell.
A growth factor or growth hormone controls the growth of an organism. A solution in chemistry is a liquid containing dissolved substances. Precipitates are solid particles in a solution that arise as a result of a chemical reaction. The sentence makes perfect sense because precipitates in a liquid are not considered part of a solution because they are not dissolved.
An ohm is a measure of electrical resistance. Copernicus argued that the Earth went around the Sun and not the other way around.
In microbiology, a culture is a growth of microorganisms for scientific study. A mole is about 6. A mole is used as a count for atoms and molecules. Avocado sounds like Avogadro. A mole is Avogadro's number. Opossums have prehensile tails, ones that can hold onto things.
The spinal column is the backbone. The student confused the words "revolution" and "resolution". Jokes Based on the Heisenberg Uncertainty Principle: The joke is based on the Heisenberg uncertainty principle, which states that you cannot simultaneously measure both position and momentum accurately.
Physics 15 and Physics According to the Heisenberg uncertainty principle, you cannot simultaneously know both your position and speed precisely. Heisenberg uncovered the uncertainty principle in quantum mechanicswhich places limits on what one can know or measure.
A black hole is an extremely dense object whose gravity is so strong that nothing, including light, can escape from within.Hooke's Law states that the restoring force of a spring is directly proportional to a small displacement. In equation form, we write. F = -kx. where x is the size of the displacement.
The proportionality constant k is specific for each spring.. The object of this virtual lab is to determine the spring constant k. Everything of importance has been said before, by somebody who did not discover it. Alfred North Whitehead () The Stigler's Law of Eponymy (a special case of the Matthew Effect) seems actually due to Robert King Merton () No scientific discovery is .
As long as they are not twisted beyond their elastic limit, torsion springs obey an angular form of Hooke's law: = − where is the torque exerted by the spring in newton-meters, and is the angle of twist from its equilibrium position in radians.
is a constant with units of newton-meters / radian, variously called the spring's torsion coefficient, torsion elastic modulus. English physicist and mathematician who was born into a poor farming family.
Luckily for humanity, Newton was not a good farmer, and was sent to Cambridge to study to become a preacher. At Cambridge, Newton studied mathematics, being especially strongly .
The Magdeburg hemispheres, around 50 cm (20 inches) in diameter, were designed to demonstrate the vacuum pump that Guericke had invented. One of them had a tube connection to attach the pump, with a valve to close it off.
Many objects deform according to Hooke's law; many materials behave elastically and have a Young's modulus.
In this section, we explain the origin of elastic properties and Hooke's law by consideration of the forces and energies between atoms or molecules in a solid. But first, an experiment. This.
