This video explains how the different particles in an atom have charges, how the different particles affect the overall charges of an atom, and how atomic models are created.

Let's learn how the Milankovitch Cycles impact climate change!

A video entitled “The Bohr Model” which describes the Bohr model of the atom and discusses the model’s importance and meaning.

Explains how to compose an electronic configuration for an element using the number of electrons that the element has.

My solutions to Free Response Question #1 from the 2018 AP Physics 1 Exam. Also included are my reflections on how to get more points on the exam.

This Short Answer question also works as a part of the AP Physics C: Mechanics...

Introducing the SN1 reaction.

In the previous tutorial, we learned about some five-membered aromatic heterocycles. Those were furan, thiophene, and pyrrole. Now let's learn about a six-membered one, pyridine. This one is ubiquitous in nature, so let's get the scoop...

An introduction to the diels-alder reaction.

The video discusses the relationship between orbital speed, orbital radius, and orbital period of objects in space. It explains how to calculate orbital speed using an equation and provides examples such as calculating the orbital speed...

Pi-donors, Sigma-donors, and Pi-acceptors: Orbital Overlap

It's time to start our survey of the periodic table, and we are going to start with just one element, hydrogen. This is the most abundant element in the universe by a wide margin. What does it do? What are its properties? What are its...

A “super-Earth” orbiting a red dwarf star has been discovered only 36 light years from Earth, according to a study published in the Astronomy & Astrophysics journal.

Postulates of Quantum Mechanics: Orthogonality of Wavefunctions

The International Astronomical Union should ‘rescind their non-scientific definition’ of Pluto as a dwarf planet, according to a five-year study

Internal Conversion and Photoprotection: Applications in Biochemistry

Orbital Assembly Corp aims to start building a huge wheel-shaped space station in low Earth orbit in 2025.

SpaceX has filed an application with the FCC, outlining its plans for the first orbital test flight of its Starship spaceship within a year.

The annual threat-assessment report of the U.S. Director of National Intelligence says China is working to dominate space and is targeting U.S. satellites.

It describes electronic configuration of the elements of group 14, their physical, chemical properties and their uses.

Black widow spiders and their Australian cousins, known as redbacks, are notorious for an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary...

Admittedly, my prior tutorial on MO theory was a little confusing, and had some errors. I wanted to make things right, so here's another one! This will clarify some of the basic concepts, and will also extend them to discuss a new...

101955 Bennu is one of Earth’s closest planetary neighbors – an asteroid roughly the height of a skyscraper, and since late 2018, the place that NASA’s OSIRIS-REx mission has called home. When OSIRIS-REx arrived on...

The OSIRIS-REx team has already pushed the boundaries of scientific exploration -- going from ground-based radar images from Arecibo in Puerto Rico all the way to orbiting a few hundred meters...

Lucy is the first mission to explore the Jupiter Trojans – two swarms of asteroids that share Jupiter’s orbit, leading and trailing the giant planet by sixty degrees. These primitive bodies are thought to be...
