DNA Scientist and Mentor Bruce Jackson, PhD, traces ancestry and solves crimes with the powerful tool of DNA.
Mathematics is about numbers, shapes, symmetry, chance, change and more. Much more! Math is not only the most rigorous mental discipline ever invented, it's among the richest, most wide-ranging and most useful. Mathematics is also central to the information revolution. Downloadable music files, DVD movies, digital special effects and secure online credit card transactions, essentially any software application you can think of, owes its existence not just to computers, but to the mathematical algorithms that run on computers.
In Episode 8, Charlie and Jordan chat about the many different species of gut microbes, explore how math is helping ovarian cancer research and investigate the smell coming from water pipes in West Virginia's Elk River area.
Salvatore Torquato, professor of chemistry at Princeton University, explains his research on the theoretical packing of pennies and how it provides new insights on the nature of randomness.
Members of the Dark Energy Survey collaboration explain what they hope to learn by studying the southern sky with the world's most advanced digital camera, mounted on a telescope in Chile.
Jere Confrey is an NSF-funded researcher at the College of Education at NC State University. Her work in mathematics education provides a valuable perspective on the challenges and opportunities around having a positive relationship with math. She is one of the #WomenInSTEM we are highlighting for Women's History Month.
It's build day for Colorado State University's Little Shop of Physics, and there's a whole lot of tinkering and experimenting going on.
The Center for Computational Relativity and Gravitation at the Rochester Institute of Technology is dedicated to research the frontiers of numerical relativity and astrophysics and gravitational wave physics. The Center is funded in part by the National Science Foundation and integrates state-of-the-art science, performance computing and scientific visualization.
When it comes to ultrafast lasers, Margaret Murnane's name is one of the best known for her work in this field of science. The NSF's Ivy Kupec sat down with this well-published scientist who originates from County Limerick, Ireland to talk further about these uber speedy lasers, science and even Archimedes.
A light bulb has the glass carefully removed, leaving the glass base and filament intact. The bulb is connected to AC electricity, and the filament quickly and dramatically burns out. This leaves the two wires that originally supported the filament separated by the glass in the base. Take a propane torch and heat the glass base (the bulb remnants are still connected to the electricity), a point is reached where the heated glass is no longer isolating the two wires from each other, but has become a conductor of electricity. As the electricity flows, the heat generated lights up the glass, the propane torch can be removed, and the glass continues to glow very brightly.
A grape makes a great dipole antenna, and makes a great (small and safe) series of sparks in the microwave.
Passing a current through water makes hydrogen and oxygen, which fill a bubble that can be ignited.
An internally frosted, large light bulb is dipped into a fish tank of water, and the total internal reflection effect produces 'other-worldly' consequences to how the bulb looks in the water. The bulb goes from white to a silvery orb. Turning the bulb on, produces a similar, but more alluring effect.
A stream of air is used to levitate a small ball--and also a light bulb.
Passing a small electric current through a mechanical pencil lead causes it to glow brightly for several seconds.
You can push a knitting needle through a balloon if you take certain precautions.
A pencil lead and some batteries make a small plasma cutter that we use to etch a pattern in aluminum foil.
