Hello, I am in high school in the United States. I am SUPER interested in mathematics and physics, and I have been researching physics and mathematics since middle school. I love it! I love theoretical particle physics and algebraic topology. If I had the choice, I would spend my entire life...

If we expect kids to be losers they will be losers; if we expect them to be winners they will be winners. They rise, or fall, to the level of the expectations of those around them, especially their parents and their teachers. Jaime Escalante Famous High School Teacher

I am aware that the grades would vary from country to country and school to school, but what kind of grades (particularly in physics and mathematics) do people who go on to become physicists (experimental or theoretical) generally tend to have in their last year of high school?

I just finished my junior year in high school. In college, I hope to major in physics and was interested in the honors versions of freshman introductory physics. These all have the prerequisite of a calculus-based mechanics course and use Kleppner as their mechanics textbook. I have so far only...

I'm looking for tested and proven technology for the high school chemistry class, can anyone suggest anything? It's a passion of mine to improve labs, and teaching lessons. Lately there has been a lot of emphasis on technology in the classroom. How do you implement any technology when there are...

1)Prove without using AM-GM :\frac{ab}{c}+\frac{ac}{b}+\frac{bc}{a}\geq a+b+c...... a,b,c >02) Prove without using contradiction : a\leq b\wedge b\leq a\Longrightarrow a=b

given a>0 find b>0 such that: \sqrt{(x-1)^2+(y-2)^2}<b\Longrightarrow |xy^2-4|<a

Using high school mathematics prove the following inequality: \sqrt{a_{1}^2+...+a_{n}^2}\leq\sqrt{(a_{1}-b_{1})^2+...+(a_{n}-b_{n})^2}+\sqrt{b_{1}^2+...+b_{n}^2}

I tried with Google but I couldn't find anything, so here goes: When I "use ln on a quantity" (I don't really know how to phrase it in english, as we just have a verb for it), say, I have n = 0.00149 kg/m*s, and I put it into the ln, so now I have ln(0.00149 kg/m*s) what happens to the SI Units...

In the IB diploma program, they ask for a "Mathematical Exploration", where I have to deal with a topic with mathematical tools. For example: How to get the perfect exit of Gymnastics Bars? In "exploration" you have to see the measurements, the angles, velocity trajectories, mathematical tools...

As the title says...I am hoping for recommendations for the 2017 summer. Specifically, Southeast US, one week residential, hopefully under or around 500 dollar physics or astronomy camp for rising 9-12 graders. Thank you very much.

I'm currently a junior in high school, and I'm really interested in physics, especially particle physics and quantum mechanics. At my school, everybody needs to do a big senior project to graduate, involving multiple papers and about 30 hours of work, usually to build something or organize a...

As someone who taught math and physics for about 20 years, I've given this some thought, and I'm convinced that the whole idea of what and how we teach these in high school is upwhacked. One of the common complaints from kids, "what is this good for". And you, know, they are right. I've had...

Hi First time poster here. I recently applied to the University of Toronto in which I intend to do the Math and Physics Specialist, this university has a particular bad reputation for killing GPA; however, I'm confident that its mostly myth and with hard work anything can be achieved. The only...

I have been learning how to read scientific Russian, and my reading material is the Soviet high school math textbook Algebra and Beginning Analysis, (1976), edited by Kolmogorov. (I've seen the title also translated as Algebra and Elements of Analysis). The Russian title is Алгебра и Начала...

Hey guys, I'm from the US and 28 years young. Was riding a motorcycle through Bali and met a guy from the UK who told me he teaches math at the international high school in Bali, but taught in other Asian countries as well. Work for 9 months, vacation for 3 months and get to live abroad. Sounds...

Hi all. I got 3 Ohms in this question (top current = bottom current hence equivalent series resistance of top 2 and bottom 2 resistors must also be equal), but is that really the right answer? There is no option for 3 Ohms so I am beginning to doubt myself.

Hello my name is JP Cruz I'm currently taking an engineering course in my high school. Its a open ended design class where we think of an idea to prototype and present at the end of the year. I need as many people as I can to take our google forums to get the best data. I'm just asking for five...

Quick background: I'm currently a junior (grade 11) in high school who is intending to major in math and/or physics in college. Recently, I had a conversation with a college counselor that turned to my interests in math and physics, including my independent studying of the subjects. The...

I am having trouble creating new ideas for a physics research paper. My group has three members and we are all interested in generators that run on renewable energy. Unfortunately, we haven't found a topic yet, and the deadline is looming. We don't have a research adviser as well because to get...

I am currently picking out my courses for grade 11 next year. I have the opportunity to take both grade 11 AP Physics 1 and grade 12 AP Physics 2 in the same year (semestered). If I do I won't have any physics courses in grade 12 instead I'll be taking grade 11 Pre-AP Chemistry and grade 12 AP...

I need to introduce Simple Harmonic Motion to a group of high school students studying physics. They don't know anything about differential equation except the method of separation of variables. Also, they have limited knowledge on complex numbers like eiωt. However, I don't want to just give...

When I press these buttons on my calculator to find the third side or an angle in a triangle, what calculation is happening? What is the logic behind it all? I know it's a very basic question, but I am only in grade 10 and have not started Math yet this year.

Homework Statement A highway is to be built between two towns, one of which lies 35.0km south and 72.0km west of the other. What is the shortest length of highway that can be built between the two towns, and at what angle would this highway be directed with respect to due west. Homework...

Does anyone here have any experience in mathematical research since high school? Or even if you only started as an undergrad, do you have any advice? 1. How did you secure the research position? Who did you talk to? 2. What area of math did you do research in? Was it necessary to know a lot...

Ok I can't tell if this should go in academic guidance or homework questions so I'll just put it here. I decided to do my high school senior project writing a paper on a recent discovery in physics. I narrowed my topic choices down to either photonic particles, exotic hadrons, or the Higgs. I...

I have read that Feynman Lectures on Physics is pretty good; however, I also read it isn't a replacement for a good textbook. So I wanted a good physics(high school level) textbook that I could read Feynman Lectures on Physics along beside it. Regarding mathematics, I have completed Calculus I...

Hi I was wondering if taking calculus 2,3, and differential equations by the end of my senior year at the local community college would be a wise choice. Would taking these math classes before i use them in physics hinder my learning? (I want to be a physicist). Would I gain an advantage in...

There is a tragic story coming out today about a school shooter in Alpine, Texas. http://www.cnn.com/2016/09/08/us/texas-high-school-shooting/ Her name is not revealed, nor are her motives. The article just says she wounded a female student and that she shot herself. The wounded student...

Hello, I would like to have a good understanding of physics at my level (level of Halliday-resnick) and to be able to solve problems. It so happens that I read a chapter and solve the all the problems and exercises and I feel I am done, I know the stuff. But then up comes a problem and I get...

Hey guys, I'm in high school and we have to do a presentation on any physics topic we like. The teacher is just trying to assess our class as it is only the beginning of the school year. It has to be a minimum of 3 min and maximum of 5 min. Are there any topics that aren't too complicated, but...

So at my high school we have to do a senior project. My initial plan was to write a book and then a piano song to go with it but I'm having second thoughts. Although mine is plenty difficult enough I see people doing internships and all this stuff that looks great on a college app. For example...

Well hello there, My name is Alex, I'm a belgian high school student (currently going to start my senior year), and I'm 17. I love this forum, it helps me a lot when I need an info about physics, the physics major and the jobs associated with physics. I joined this forum because I myself have a...

Here is a thread of challenges made especially for high school students and first year university students. All the following problems can be solved with algebra, trigonometry, analytic geometry, precalculus and single-variable calculus. That does not mean that the question are all easy. For...

Hello, I have often heard special relativity was not too difficult to study. I was wondering as a 6th former what knowledge is needed to do so and if it was even possible at my level. If yes does anyone suggest any good books or websites? I am searching for a more in depth mathematical...

I was wondering if there was any high school teachers here. Have any of you guys gone right into teaching at a public high school after graduating. I've spoken to a couple different people. One of them being an ex-high school teacher (now university instructor) and he told me that with my...

I am in high school and my school offers very little in the way of higher level STEM classes. I want very badly to delve deeper into this topics so I want to take college classes over the summer. I want to take a Computer Science class and if possible I want to take an Enginnering or Science...

I know this question has been asked before but I have only found threads for it at an undergraduate's level of understanding and I am just finishing ninth grade. How does the double slit experiment prove superposition? What led me to ask this question, was that, since when you close one slit the...

Let me preface this by saying I am in the ninth grade: I ended my grade 9 math course with a 60%. Why, one might ask? Because I was lazy and not thinking about my future. It's my own fault. I am going to retake the course online by correspondence and do my best. I think I have potential and...

The book Physics Principles and Application by Douglas C Giancoli can give me the full curriculum in physics from grade 9 to 12 ? Or I need another book to cover all physics learned in high school ? All equations laws ... ?

Hopefully this is the pot of gold I have been searching for on getting help. I am a Sophomore. Over the course of this entire school year I have really struggled through my Honors Chemistry course. I really don't know what it is, I will say the lectures bore me to death, but I power through them...

Hi All, I recently decided to go after a Physics B.A. with a concentration on teaching. This degree takes away some of the upper-level physics courses you need to take for the B.S. or regular B.A., but now requires a minor in education. So, along with the general courses and four physics...

Hello. I'm currently a junior in high school and I'm interested in pursuing an academic path in physics at a university. My interests have always been in the math and sciences, although I will admit that I probably haven't even been exposed to some of the more complicated concepts, but I try to...

What are the best physics and math books that countains all the information needed for high school I need internationals books that have the best curriculum from the grade 9 to 12 . The main thing is when I will learn physics in the university I don't want to stop on anything without knowing it .

I got accepted into my states's residential high school and am going there next year for my junior and senior years. For my junior year I am doing: AP English Lang AP US History AP Calc BC AP Chemistry AP Physics C M and EM (combined) AP Comp Sci I am taking these courses to satisfy prereqs...

Is it possible to replicate the Faraday rotation experiment for a high school junior? I am in honors physics (IB) and have been taught about waves, electromagnetism, energy transfers, etc. My physics teacher will guide me if I choose to do this. Is the experiment too ambitious?

I want to learn high school physics and math but using the international curriculum I want to see everything taught at high school in those books from grade 9 to 12 any suggestion ?
