Darryl E Berry Jr – STEM

My site for discussing math and science. Here you can sign up for tutoring and peruse my future endeavors such as article and book reviews, science and math problem walkthroughs, etc.


STEM stands for science, technology, engineering, and mathematics.

My focuses are in physics and astronomy, which necessarily includes plenty of mathematics.


“Any system of knowledge that is concerned with the physical world and its phenomena and that entails unbiased observations and systematic experimentation. In general, a science involves a pursuit of knowledge covering general truths or the operations of fundamental laws” – Britannica


“The application of scientific knowledge to the practical aims of human life or, as it is sometimes phrased, to the change and manipulation of the human environment” – Britannica


“The application of science to the optimum conversion of the resources of nature to the uses of humankind” – Britannica


“The science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects” – Britannica


“Science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In the broadest sense, physics (from the Greek physikos) is concerned with all aspects of nature on both the macroscopic and submicroscopic levels” – Britannica


“Science that encompasses the study of all extraterrestrial objects and phenomena. Until the invention of the telescope and the discovery of the laws of motion and gravity in the 17th century, astronomy was primarily concerned with noting and predicting the positions of the Sun, Moon, and planets, originally for calendrical and astrological purposes and later for navigational uses and scientific interest. The catalog of objects now studied is much broader” – Britannica

Tutoring Services

I have worked professionally as a Tutor and Learning Assistant at the college/university level. I can help with physics, astronomy, and mathematics from grade school up to an intermediate undergraduate level.

Regular Sessions

Both Students and Those Curious

  • Students can improve their grades
  • General improvement of science and math literacy
  • If encumbered by a false ideology, such as flat Earth, get some assistance getting beyond it!

“I was just absolutely obsessed with truth. Obsessed with truth. And so the obsession with truth is why I studied physics, because physics attempts to understand the truth of the universe. Physics is just what are the provable truths of the universe – and truths that have predictive power.”
