Bending Beta Particles with Magnets

By George Dowell There are many different types of atomic and nuclear radiation. “Atomic” refers to the atom as a whole, but the commonly accepted definition of atomic reactions are those that originate in the electron shell area of the atom. “Nuclear” on the other hand is specific to the nucleus of an atom. Some radiation consists of particles of matter, betas and … Continue reading…

Magnetic Fields and How to Measure Them

Figure 2. Circuit diagram for a simple magnetic field readout.

There aren’t a lot of fields in physics to study beyond gravity, electromagnetism and the strong and weak nuclear forces. Since the last two are essentially impossible for an amateur to study, that only leaves gravitational and electromagnetic fields. Continue reading…

Citizen Science Musings: Making Amateur Scientists

One of the telescopes featured in Ingall's inaugural column,made by E. L. Worbois, 127 Adam Street, Tonawanda, New York.

This past week I was graciously invited to speak to a local astronomical club, the Peninsula Astronomical Society. After some consideration, I decided to talk about the role of Scientific American’s famous, much-loved and equally-missed column, “The Amateur Scientist” in the growth of amateur astronomy. Continue reading…

The Doppler Shift

Most of us have used the Doppler effect unconsciously to estimate the speed of a car that approached quickly from behind. The sound of the approaching car has a higher pitch than the sound as the car leaves you behind. Continue reading…
