Particles
Ordinary matter is made of these.
Fundamental particles
Neutrinos come in these three flavors.
Electron, muon and tau.
These are the four fundamental forces of nature.
Gravity, weak, electromagnetic, and strong forces.
Fermilab scientists build these large machines to study fundamental elementary particles.
Accelerators and detectors.
An object has a shape symmetry if it looks same after this is applied.
Transformation (rotation or reflection).
These are the lightest and heaviest fundamental particles.
Neutrino and top quark.
This is the phenomenon of neutrinos changing from one type into another.
Neutrino oscillation.
Only particles that have these properties are affected by the electromagnetic force.
Electric charge and/or magnetic moment
Protons are accelerated at Fermilab almost to this speed.
The speed of light.
An object must have this property to exhibit a rotational symmetry.
It should look exact same after you rotate it less than one full turn.
These fundamental particles are massless.
Photon and gluon.
These type of neutrinos are born inside the sun.
Electron neutrinos.
These forces act only at the subatomic scale.
Weak and strong nuclear forces.
The protons that Fermilab accelerates come from this.
Bottle of hydrogen gas.
Square has these symmetries.
Rotational and mirror symmetries.
These fundamental particles were discovered at Fermilab.
Top quark, bottom quark and tau neutrino.
These particles are born when neutrinos interact with matter.
Electron, muon and tau lepton.
These particles are the carriers of the electromagnetic force.
Photons.
These are the two basic types of particle accelerators.
Circular and linear.
An object must have this property to exhibit a mirror symmetry.
It must have two halves that are mirror images of each other.
This quark is as heavy as a gold atom.
Top quark
Only these forces can affect neutrinos.
Gravity and weak.
This force is the weakest fundamental force.
Gravity.
Only this kind of particles can be accelerated in a particle accelerators.
Electrically charged particles.
These physical laws are found when symmetry is observed in nature.
Conservation laws.
