White Dwarf Stars
When stars die, they don’t all go out in a blaze of glory. Some fade away — quietly, beautifully — leaving behind a glowing core that tells the story of…

The Periodic Table
The Periodic Table is a scientific chart that arranges all known chemical elements according to their atomic number (the number of protons in their nucleus), electron configuration, and recurring chemical properties.

The Quantum State
A quantum state is simply a description of everything we can possibly know about a particle at a given moment.
It tells you things like:
where the particle is likely to be,
how fast it’s moving,
what energy level it’s in,
what direction it’s spinning (its “spin”),
and other properties that define it uniquely.

Fermions
Fermions are a class of particles that make up matter itself.
Electrons, protons, and neutrons — the very things that form atoms — are all fermions.
If you could zoom in on your body at the tiniest scale, everything solid about you would be made of these particles.
But what makes them special isn’t just what they’re made of — it’s how they behave.

The Pauli Exclusion Principle
Atoms are made up of a nucleus (protons and neutrons) surrounded by electrons. These electrons don’t just float randomly — they live in specific “zones” called orbitals, like seats in a theater.
Each seat (orbital) can hold two electrons, but only if they spin in opposite directions.
Once that seat is filled, no other electron can sit there — it has to find another orbital or energy level.
That’s Pauli’s rule.

Electromagnetic Resistance
Electromagnetic resistance is the pushback that happens when two negatively charged things (like electrons) get close.
Think of it like two magnets. Try pushing the same poles (north-to-north or south-to-south) together — they resist each other. You can’t make them touch no matter how hard you try. That’s because their magnetic fields are repelling.

Quark Stars
A quark star is a hypothetical type of star that forms when a dying massive star collapses beyond the neutron star stage but stops short of becoming a black hole. Inside, matter is crushed so tightly that quarks — the fundamental building blocks of protons and neutrons — break free, forming an exotic soup called quark matter.

The Wiggers Diagram
The Wiggers Diagram is a classic graph in physiology that represents all the events of the cardiac cycle in one picture.
It combines:
Electrical activity (ECG)
Pressure changes (atria, ventricles, aorta)
Volume changes (in the ventricles)
Heart sounds (phonocardiogram: S1, S2, etc.)
This is why it looks so complicated—because everything is happening at once. But if we follow it layer by layer, it makes sense.

Escape Velocity — Explained Simply
Imagine you’re standing on Earth, holding a ball. You throw it upward. What happens? If you throw gently, it comes back down quickly. If you throw harder, it goes higher…
