Constantly Learning and Improving

A quasar or Quasi-Stellar Object (QSO), is an extremely luminous,
active galactic nucleus (AGN),
in which a supermassive black
hole (SMBH) with a mass ranging from
millions to billions of times the
mass of the Sun is surrounded
by a gaseous accretion disk.

Supermassive Black Hole

A black hole is a region of spacetime where gravity is so strong that nothing—no particles or electromagnetic radiation (light) —can escape from it. A supermassive black hole (SMBH) is defined as a black hole with a mass above 0.1 million to 1 million M☉

Hubble Tuning Fork

In the Hubble Tuning Fork galaxy diagram, galaxies are arranged along the fork handle based on their structural properties, or morphology, how elliptical they are: the more spherical galaxies are furthest from the tines of the fork, and the more egg-shaped ones are closest to the end of the handle, where it divides into two prongs. The two prongs of the fork represent the barred spiral galaxies on the bottom prong, and the unbarred spiral galaxies on the top prong.

A life long passions in astronomy coupled with my Bachelor of Science in Physics, I fell in love with Astrophysics, the moment of I learned of its existence. At the end of my degree I had the amazing opportunity to create a computational astrophysics project. It was here I reignited my love for technology and began learning my first object-oriented programming language, Python. I now work for a small software company where I get paid to learn as much as possible every day.

So now that you know I have a background in STEM, here are some other things about me. I am a cat mom of two lovely boys, a sister to three siblings, an auntie of four children, and survivor of traumatic events. So as you can see I am not just an intelligent person, I also have a lot of life experiences many can learn from.

I wanted to create STEM Learning to spread my love and knowledge of all things STEM to others who would like to learn more. It was not until I began putting it all together, I decided I wanted to add some personal experiences to the website, as I felt living during a pandemic others may need to learn more than just about all things STEM. Since I have experiences others can learn from, I would like to share those as well.

Science is the pursuit and application of: knowledge and understanding of the natural and social world following a systematic methodology based on evidence. Natural science is the study of the physical world: life science and physical science. These two branches may be further divided into six disciplines. Life science as: biology and environmental; and physical science as: astronomy, chemistry, earth science, and physics.


Technology is the application of scientific knowledge for practical purposes, especially in industry. It is the sum of techniques, skills, methods, and processes used in the production of goods, services, or in the accomplishment of objectives such as scientific investigation.


Engineering is the creative application of scientific and mathematical principles to solve problems by: designing or developing structures, machines, apparatus, or manufacturing processes, or to forecast their behaviour, under specific operating conditions. Engineers figure out how things work and find practical uses for scientific discoveries.


Mathematics is the science of: numbers, quantities, structures, space and change, and the relationships between them.
