I am in 8th grade and 10 hours a day free time and i am highly motivated to learn some particle physics. What should i start with?
Hello everyone! I'm new to this forum, and I've tried looking at all the conventions on the forum, but if anything I say is out of line, please speak up! With that out of the way, I've added some of my background in physics in the spoiler, with the main questions below that.

I want a suggestion on a book for learning HTML programming. You all know what my level is...which is NOT MUCH. I just want to get a book that is not too hard to learn. One that I can experiment and play with.
Thanks
I am currently facing a problem with my quad bike handlebar starter switch.
When i am turning it on it does humming but it seems as if it is not getting the power to its alternator

Hey all!
Today I took my car to the shop for some starter issues. They told me that the starter had been damaged by a battery with a higher CCA rating than was safe for the starter motor and it burned out my motor slowly over time. I feel like they may be BS'ing me, but I'm not sure.
I know my...

Hello,
I have ordered an arduino atarter kit and plan to explore some programming and electronics.
Do you have any interesting project ideas for me?
Thanks.
Hi I'm very new to this so bear with me lol. I'm trying to plan out a project for building a diesel powered car and I want to use an of the shelf pneumatic starter for novelty but I don't know how much volume I need. So the starter requires 120 psi @500scfm. My idea is to use scuba tanks or...

I found a motor I think is from an old AC unit in the recycle. It is a 1/4 HP, 265V, 1.20A AC motor. I've been looking to make a low-torque sander and was thinking about using this as a a drive motor. I know the starter capacitor is there to provide an initial burst of current to get it up to...
A brief introduction: About 6-7 months ago I got really interested in making various types of bread. The one bread that I really wanted to make was sourdough: it is one of the oldest breads in the world, and perhaps one of the most universally loved, described by some as being "the world's best...

Hi Guys,
I have a model gas turbine that is driven by an ecu ... the ecu starter output is 12.6volts but the starter motor is rated to 6volts.
The ECU can easily supply 20amps although the starter motor is rated to 5amps max efficiency.
I need to drop the voltage from 12.6volts to...

Hi,
This is my first post. I've been mulling over whether to go back to university and study physics for years now. I've always had a passing fascination but have been constantly aware that I'm picking up the glamourous 'new scientist' end of the field and that real physics is, in all...
Hi, I got a small problem which I'm not sure I'm solving correctly. A small induction motor has a short circuit current equal to 5 times the full-load current. I need to find the starting torque as a percentage of full load torque if the motor is started by a star-delta starter. It is also known...
