Congratulations to @Ted_Prohowich. Your question was chosen for tonight’s Ask Greg and the Panelists.
@Ted_Prohowich What's your back to school advice?
Congratulations to @steve-allen and @wilbner. Your questions were chosen for tonight’s Ask Greg and the Panelists.
@Steve-allen What pet did you always want but never got ?
@Wilbner What food have you "overdosed" on many years ago, and refuse to eat now?
Mark and I went for a hike at Shell Ridge Open Space in Walnut Creek today, and the weather felt tropical. Beautiful clouds and warm. It was absolutely beautiful!
I did, however, make the strategic decision to stay a good distance behind Mark—not because I needed the exercise, but because he was on the phone making a customer complaint. 😂. I think complaining, justified though, gives him a natural high.
I was there to enjoy the beautiful scenery, the fresh air, and this gorgeous protected open space. I had no interest in adding “listen to Mark complain” to my Friday itinerary.
Sometimes a little distance is good for a marriage. Especially when one person is on hold. 😂
How was your Friday?
I had a complete hysterectomy when I was 46. The military wouldn't put me on hormone replacement because I smoked cigarettes. They put me on a low-dose antidepressant. It was tough. Really, really tough.
I still got up at 0315 after I recovered, commuted, worked and got home by 6:00 p.m.
You know what I didn't do? Kill my kids, even though sometimes they were adolescent assholes.
Morning!!
Some Saturday Morning Physics & Engineering History -
Michael Faraday demonstrated electromagnetic induction on August 29, 1831, using his induction ring-coil apparatus—the prototype for the first electrical transformer.
The Experiment
The Apparatus: Faraday wrapped two distinct insulated coils of copper wire around opposite sides of a soft iron ring.
The Setup: He connected the first coil to a battery and attached the second coil to a galvanometer (a meter to detect electric current) without any direct power source attached to it.
The Discovery: When he turned the battery on or off, the meter on the second coil briefly jumped, proving that a changing magnetic field inside the iron ring induced a transient current in the secondary wire.
Historical Significance
Electromagnetic Induction: The experiment proved that electricity could be generated from magnetism, leading directly to Faraday's law of induction. [1, 2]
Modern Engineering: This foundational breakthrough made modern electrical ...
