Device using small disc magnet
September 6, 2017
Good morning Ron. My son and I are developing a low tech medical device that relies on the attraction between a small disc magnet 20 mm x 2 mm and a similarly sized flat washer. We're having a problem with the amount of attraction between the two and need to increase it and are thinking about increasing the size of the magnet or the washer but are constrained in doing this due to physical dimensions. Is there anything readily available such as a flat washer or disc with a higher than normal iron content that would cause the magnet to be more strongly attracted to it? Many thanks!

You might try a Neodymium disc magnet. They are small, strong and inexpensive and can be bouht through Amazon.com or other outlets.
I hope that helps. Best wishes for success with your device.
Electrostatic induction and rice
September 5, 2017
Electrostatic induction or electrostatic generator that can stick with plain dry rice or not ???
daksha - India (28213)
An example of rice being affected by static electricity can be explained in Rice grains sticking to a polythene bag.
Reflecting sound from concrete wall
September 3, 2017
what frequency can a concrete or a stone reflect back.
Kapil - India (28210)
Within the range of human hearing (20 Hz - 20,000 Hz), the higher frequencies are reflected much better than the lower frequencies. Of course, much depends on how smooth the concrete surface is.
Gaining knowledge in Buddhism
September 3, 2017
I am interested in gaining knowledge in Buddhism
With good character knowledge
Dermot - USA (28211)
I plan to add material on how Buddhism encourages good character. But also, I will be adding material explaining Buddhism in our Religions section. See Noble Eightfold Path in Buddhism for some information.
Wants us to remove information
September 1, 2017
I am a high school librarian. I am planning to do a We Didn't Start the Fire unit with my AP United States History students. They will each have a line of the lyrics to research. They will each create PowerPoint slides for each historical event, person, or thing named. It will all be compiled into one huge PowerPoint. Students will present their slides to the class. I am very excited about doing this with them. I would like to respectfully ask if you could possibly take this info down. I don't want my students to just copy from your site.
Michelle - USA (28206)
It is a good project for your students to study the various historical events.
However, asking us to remove information from our website is out of line. What about the many other resources on the Internet? Should they also be removed?
A better lesson is to teach the students to avoid plagiarism and to cite their resources.
Best wishes for success in your class.
Would the Gravity book be helpful?
September 1, 2017
Hi, I will be working on a physics project this fall semester and was wondering if your book would be helpful in assisting with the project and/or project ideas.
Ashley - USA (28207)
The advantage of the book is that everything is in one place, such that it is easier to navigate. However, all the material on Gravity and Gravitation is on the website. You can pick and choose what you want to see.
Best wishes for success in your Physics project.
We wanted to say thanks!

Good Afternoon :)
I'm Katie Vogel, a full time mom and tutor during the summer. I'm reaching out to you because my daughter Peyton is a girl scout and is trying heard to earn her volunteer badge this summer. She's been volunteering at a local animal shelter and helping with some of the pamphlets and adoption events. A lot of it is informational, so she had to do her research. She found your page, http://www.school-for-champions.com/animalhealth/resources.htm . She really enjoyed it - thank you so much for that!
In return, she wanted to share with you this article http://dentalassociatesnova.com/guide-to-dental-health-for-your-pets/ . It's all about dental health for you pets. This was perfect for us since we didn't know too much about it! She was thinking it would make a great addition to your page, what do you think?
Whether you add it or not - we wanted to say thanks! We learned a lot of great things after reading the resources on your page. If you do decide to add it, please let me know. Peyton would be so excited and would show her fellow scouts too!
Katie - USA (28201)
I'm glad Peyton found the resources page useful to her. There are also a number of Animal Health articles shown on the side menu.
Thanks to Peyton for the Dental Health for Pets resource. I added the link to the Animal Health Resources page and plan to add some material on dental care for pets. Many overlook that situation.
Best wishes in getting the Volunteer Badge. I'm sure she will succeed.
What if matter did not change its state?
August 25, 2017
Explain that what happened if there would be no change in states of matter?
Aamish - Pakistan (28197)
If all matter stayed in its existing state or phase, ice would not melt to become water, and water could not boil into steam. Also, there would be no evaporation of water. Just these factors alone would affect living beings in a short time.
Hearing high frequency pitches
August 25, 2017

Some people are sensitive to high frequency electrical signals, such as come from high power electrical lines. Also, a defective microwave oven can emit electrical signals that affect some people.
For people with older metallic filling in their teeth, high frequency electrical signals can even heat of the fillings. It is good to check with your dentist on this issue.
Such sensitivity can cause anxiety attacks, as well as other symptoms. If you have some device like a pacemaker, you should make sure it is not defective and causing you some problems. It is good to check with your doctor to make sure devices working properly.
I hope this helps you solve your problems. Best wishes for good health.

I never knew how to use a calculator other than the basic + - * % =. I wanted to learn and came across your page. The way you explain/teach is so easy to understand and doesn't present with a bunch of hogwash like other things I came across when online. I am going to also explore the other topics you have available. So, I'd just like to say thank you.

I'm glad the material was useful to you. Best wishes for success in learning new things.
Is pressure distributed on a bench?
August 15, 2017
This article of you on pressure helped me greatly. But I still have some confusions. Such as-
If we apply force with the surface of our hand on a big bench then will the force be distributed throughout the whole area of the bench or it will just act on the portion of the bench equal to the area of our hand?
Dise - USA (28183)
The pressure on the bench will be just on the area where you push with your hand. Think of how a pillow will compress where you push your hand on it.
However, the force you apply can move the whole bench.
August 15, 2017
I stumbled upon your site and found the infographic you shared: "16 Boring Words & What to Use Instead".
Great stuff! I also really liked it. Thank you for sharing.
Donna - USA (28184)
I'm glad you liked the material.
Permission to use images
August 14, 2017
I would like to use the phase diagram figures that you have on this page: http://www.school-for-champions.com/science/matter_states_pressure.htm
in an article that I am writing for the Health Physics Society. I understand that I need permission to use the figures. Is that possible that I could have permission to use your figures?
Thanks so much,
Linda - USA (28181)
Yes, you have permission to use the diagrams provided you cite the source.
Best wished for success in your article. Let me know when it is published.
Thanks for this opportunity

Thanks for this opportunity

I wish you success in your endeavors. I am sure you will be a champion.
Where are the attractive forces equal?
August 5, 2017
At what distance from the earth should an object lie between the earth and the sun such that the attractive force of the earth on it is equal the attractive force the sun on it , given that the distance between the earth and sun is 150million Km and the mass of the sun =3.24mass of earthh
- USA (28163)
The point where the attractive forces are equal is at the center of mass (CM) between the Earth and the Sun. See CM between two spheres for the equation.
