Microsoft Works was a productivity software suite developed by Microsoft and sold from 1987 to 2009. Its core functionality included a word processor, a spreadsheet and a database management system. Later versions had a calendar application and a dictionary while older releases included a terminal emulator. Works was available as a standalone program, and as part of a namesake home productivity suite. Because of its low cost ($40 retail, or as low as $2 OEM), companies frequently pre-installed Works on their low-cost machines. Works was smaller, less expensive, and had fewer features than Microsoft Office and other major office suites available at the time.
Having taught physics for several years now, both algebra-based and calculus-based, and seeing what works and what doesn't in labs, I thought I would post some of my findings here in one place for your edification.

Tell me if I'm on the right track. Any command in a computer program when you break it down is really just a combination of different digital logic configurations (AND, OR, NAND, etc.). Then the microprocessor activates some of its transistors that are in the right configuration to perform that...
Forgive my ignorance here, I'm not a physicist, but the exact nature of gravity beyond the Event Horizon has me a bit stumped.
Say I cross the Horizon of a Supermassive Black Hole, meaning the pull on me isn't really that much stronger than Earth's pull initially - why can't I then escape...
Hello dear physicists,
Have you ever published some scientific paper works ?
I'm a little confused about that publishment thing.Can I publish my works for exaple to Annalen der Physik and what are the norms for the publishment ?
Can I send any of my works to any physics journal ?
Thank you...
Hello there. Recently I was tasked to design a lab experiment using a ballistic pendulum.
Now I understand that all the sources of the internet say that by principle of conservation of linear momentum,
(1/2)(m+M)V2 = (m+M)gh , or V2 = 2gh
And then using principle of conservation of energy, we...

The fundamental question, what is the reference geometry where images can be fused to form a 3D panorama? In other words, how images are assigned a 3D position? Does it require a gyroscope to be built in camera to define its position per image of the interest? Or just it simply fuses images with...
I need to know how a pair spectrometer works but I can't find a book that explains it in detail. They say that it has three crystals located in a line and the beam is collimated on the central crystal and somehow this signal is only analyzed when there are simultaneous signals from the other two...
So I understand that a battery consists of an anode, cathode, and electrolyte.

If I'm right, all electronic component works on quantum probability. I was thinking all these electronic component works on classical physics only. Because probability will not produce 100% result, as and when desired.

Hi.
Could anybody tell me how does a purse hook works?

This must have been asked before. But never mind here I ask it again to convince myself.
Newton's Second law says \vec{F} = m\vec{a}
Now if we put \vec{F} = 0 here we get \vec{a} = 0 which is Newton's First law.
So why do we need to state First law as a separate law?
Before I asked this I did...

Why does charge get accumulated on the plates? Isn't that a higher energy state than battery?
