Philosophers & Scientists
Ancient Greek philosopher who gave us the word atom meaning indivisible or unable to cut down any further.
Who was Democritus?
This law states that energy is neither created nor destroyed but is transformed.
What is the Law of Conservation of Energy?
Because they are much too small than the waves of visible light, we cannot see them so what we know about them has been inferred from thousands of experiments.
What are atoms?
Nothing ever really touches anything else. This is the force of electronic repulsion that keeps them apart.
What is electromagnetic force?
With 70% of the earth's surface covered with water, the water cycle, an atmosphere to trap heat and regulate temperature, the earth is positioned just the right distance from the Sun in this zone.
What is the habitable zone?
In 1803, this English scientist published the first fully scientific model of the atom confirming that Democritus was correct that everything was made of indivisible atoms.
Who was John Dalton?
The Cosmic Microwave Background is believed to be left over from the original creation event recorded in Genesis 1:1.
What is the Big Bang Theory?
Of these two subatomic particles in the nucleus, the neutron is a tiny bit heavier than the other particle that has a property called a charge that is responsible for electricity and everything electrical in nature.
What is a proton?
This nuclear force is the strongest four fundamental forces. This force only operates inside the nucleus of atoms so that if two protons get this close together the strong nuclear force grabs them and binds them together, releasing energy in the process.
What is the Strong Nuclear Force?
The liquid iron core of the earth creates a magnetic shield around the earth to protect us from the solar wind, a spray of high energy protons and electrons from the sun.
What is the magnetosphere?
In 1897, this English scientist's atomic model the Plum Pudding Model described a cloud of positively charged material with thousands of negatively charged particles embedded in it.
Who was JJ Thomson?
This energy between stars and planets is like the energy stored in a bent bow.
What is gravitational attraction?
This third particle inside the atom weighs about 2,000 times less than the protons but with the same strength as the proton yet this particle has a negative charge.
What is an electron?
This naturally occurring nuclear reaction in which an atom of a radioactive element spontaneously changes the composition of its nucleus by the emission of particles and or electromagnetic radiation.
What is nuclear decay?
The book of Genesis and current scientific theory both hold that the universe had a beginning, but science has not always held to this until this astronomer discovered that the galaxies are all moving away from each other, so the Big Bang Theory was formulated after 1929.
Who was the astronomer, Erwin Hubble?
In 1909, the English New Zealander scientist's model of atomic structure was a tiny nucleus containing the positive charge and almost all of the mass with negative electrons surrounding the nucleus with most of the atom empty space.
Who was Ernest Rutherford?
Light exhibits the properties of both waves and particles. For this reason, we say that light has a "dual nature."
What is electromagnetic radiation?
Atoms gain and lose electrons and when they do, they are not electrically neutral, so they have a net charge either negative or positive.
What are ions?
A single pole of a magnet that (north or south) which cannot exist by itself.
What is a monopole?
This 16th Century Christian astronomer said that this finely tuned universe was "built for us by the Best and Most Orderly workman of All" namely God.
Who was the astronomer, Nicolaus Copernicus?
In 1932, building on the work of Danish scientist Niels Bohr's quantum model in which electrons reside in orbitals of various shapes nested around the nucleus, this English scientist discovered the neutron.
Who was James Chadwick?
In 1905, this German Swiss Physicist announced that energy is quantized meaning that it comes in little lumps called quanta.
Who was Albert Einstein?
In an atom, every electron has a very specific amount of energy, and these electrons are arranged in the atom based on how much energy they have, and they buzz around in clouds.
What are called orbitals or shells?
In 1915, Einstein's General Theory of Relativity envisioned geometrical in nature meaning that the presence of any object with mass warps the dimension of space and time which Einstein called by this term.
What is spacetime around a massive object?
Science depends upon the regular behavior of the world around us. If there were no laws of nature, there would be no science. There would be no people, either.
What are the Laws of Nature?
