My answer looks like this (translating from my pen+paper notepad): a+b = a+a*b 1+1*4=5 2+2*5=12 3+3*6=21 8+8*11=96 my friend got 40, which I can also see. I am not sure who is correct. Please let me know and let’s put our heads together and have fun.

I know that absolute zero is impossible to achieve but we can get close. According to google the coldest temperature ever reached in a lab was 0.006K. Do you think this is because while the atoms are moving very slow relative to the observer they are still moving at the velocity of Earth's...

Hello physics forums I am newly started teacher at end high school level. I am looking for ideas for a case which involves a course called technology, where the students learn how to create a product + one of the following four courses: Physics, communication & IT, biotechnology and design...

Afternoon every one. I am a first year engineering student in NZ, For my midterm break report I have to design and make a catapult that can meet these specifications. - hit one target within a 0.1 m radius of a target that is 1 m away horizontally from the base of the model catapult. - hit one...

Hi, I'm trying to design a contraption for a project that will move an item/box up and to the side. I have a picture of what it should look like and how it should look like but I need help with the mechanics of it. The box's starting position is In the ground and under a slap of metal or wood...

I know several math formulas, like which I will write below. \int_{x_0}^{x_1} f(x) dx \frac{\int_{x_0}^{x_1} f(x) dx}{x_1-x_0} \frac{\int_{x_0}^{x_1} f(x) dx}{2} f(x_1) - f(x_0) \frac{f(x_1) - f(x_0)}{x_1-x_0} \frac{f(x_1) - f(x_0)}{2} \frac{f(x_1) + f(x_0)}{2} And I know too that...

I am currently a sophmore in college as a mathematics major. I see that a lot of the career advice on this page that encourages me to obtain job skills, something applicable to the real world job market. Does anyone have any examples of specific careers in applied mathematics/physics/computer...

To Mars Obama just proposed having astronauts orbiting Mars in the mid-2030s. I already know that in 2035 we'll have a fairly close approach to Mars. However, this time frame is interesting for another reason. Sending a vehicle in orbit around Mars is all we really need to do to set the stage...

Hi I am soon (well... in 8 weeks) sitting my OCR A2 level (Advancing physics) examination. The exam is based mainly on experimentation and data handling techniques. Anyway, I have been given an official "pre-release reading" with loads of information in it. What I need to do now is...

I am currently a junior at a 4 year university and I will be graduating in the spring of 2010 with a BS in physics. I'm having a very hard time deciding what to do after I graduate, so I thought I'd ask around for ideas. My problem is that I have a lot of interests, but I don't know how to...

I have a good idea for a linear actuated drive system for automobiles and engines in general. I need a recommendation for a linear actuator that has a stroke of up to 18 inches, can perform very fast cycles of actuation and retraction in a controlled fashion, around 25 to 50 Hz. Needs to provide...
