Nobelist George Thomson is the son of J.J. Thomson, a Nobel Prize winner who discovered this negative particle
What is an electron?
Physics has been defined as “the science of matter, motion and” this, the “E” in a 1905 equation
What is energy?
P: Scheme up this figure with a polygon for a base and triangles with a common vertex for faces
What is a pyramid?
To produce energy, scientists are experimenting with plasma, a charged medium, sometimes called the fourth one of these after solid, liquid and gas
What is state of matter
The first shell around a nucleus can have a maximum of this many electrons
What is two?
In 1915 Australians William H. and William L. Bragg shared the prize for their analysis of the structure of crystals via this type of image
What is an x-ray?
Abbreviated “N”, it’s the ordinary term for the perpendicular force you’re exerting on a book to keep it in contact with the wall
What is normal?
E: It’s a closed, oval-shaped curve
What is an ellipse?
As fuel, fusion reactors use deuterium and tritium, isotopes of this element that contains one proton and one electron
What is hydrogen?
Explained by Einstein in 1905, this “effect” of light on subatomic particles is fundamental to modern physics
What is photoelectric?
Last name of father and son Niels and Aage, who both won the Nobel Prize in Physics
Who is Bohr?
“Classical” this branch of physics deals with motion and forces; the “quantum” branch, with subatomic particles
What is mechanics?
A: Two angles that share a vertex and a side are this, like neighbouring lots
What is adjacent?
Scientists are experimenting with plasma as a means to sterilise food containers and destroy spores of these microorganisms of the kingdom Monera
What are bacteria?
It’s the term for the minimum amount of fissile material needed to achieve a self-sustaining chain reaction
What is critical mass?
Marie Curie and her daughter Irène Joliot-Curie both won the Nobel Prize in this category
What is chemistry?
A stapler is an example of this simple machine with the hinge serving as the fulcrum
What is a lever?
R: A multiplicative inverse
What is a reciprocal?
In generating fusion energy, scientists are experimenting with this lightest metal, also used in mobile phone batteries
What is lithium?
The smallest discrete amount of radiant energy is called this, also a name for a branch of physics
What is quantum?
Manne Siegbahn and his son Kai Siegbahn were both pioneers in spectroscopy, the study of the interaction between electromagnetic radiation and
What is matter?
In physics, it means empty space; when you feel like you’re working in one, you feel isolated
What is a vacuum?
O.P.: two numbers whose position is important, so (X,Y) is different from (Y,X)
What is an ordered pair
The plasma in the reactor is heated to about one hundred million degrees Celsius, more than six times hotter than the sun, and has to be confined using this type of field
What is magnetic?
Henri Becquerel was all aglow when he won the 1903 Nobel Prize in Physics for discovering this property of matter
What is radioactivity?
