Hello everyone Definition and 26 Threads

Hi everyone. my name is Antony and I really love science. I am here to learn and share my learning but I would like to learn first. I decided to join this forum because I am studying electrical engineering and I would like to know more about this field in a world and abroad point of view.

Hello everyone, I am new here and in my every day life I usually have plenty of questions but not so much answers. You guessed it right, I am here precisely to seek these answers because it seems I will always find here someone to think about my questions and, hopefully, help me to increase my...

i want to know about the physics of everything?

Hello there! It's a bit strange to registre on a forum about Physics and state having "no background". We have made this choice because we consider it is not "the background" which counts but the Relevancy, the Accuracy of the Logic, Maths and Epistemological points of view which are Provided...

Hi there,my name is Jacqueline.Nice to meet you.

Hi folks, My name is Andreas and I'm from Munich, Germany! I'm an undergrad in Technology Management and highly passionate about new disruptive technologies in the field of engineering. Hoping to find and participate in great discussions in this forum! Cheers to y'all! Andreas

Hello evervone can somebody help me, to calculate the cascade amplifier, if somebody can tell me the formula? of to explain me? i am reading the book "electronics devices circuit and theory" page 201-202 i don't know how come the value 2.50v, 1.25v, 1,87v see the photo down...

A big hello to everyone in this forum, my name is Kilian, I'm 19 years old and from Berlin, Germany. Right now I'm in the second Semester of university studying for becoming an electrical engineer. As you might think I'm pretty interested in electronics and I've got several projects in mind...

Hi, I believe I am supposed to introduce myself. My name is LukeH and I am a retired blue collar worker with a general high school education. Some algebra and no higher math, no chemistry or physics, the only science I studied was biology for three years because it really interested me. During...

hello,everyone! I am Atosi and I love physics!

I have had the privilege to watch the web grow from where myself and a friend got to xmit and receive single 4 bit words on a bell labs 110 baud acoustic coupler to the behemoth is it today. It's been a great trip. I have been a lurker on this site for years, and find the level of reporting...

I'm an astrophysics student. Wish I could math better. Good luck to you all in your studies.

Hey everyone, I am Anushka from India. Honestly, I have my exams approaching and since my teachers are being of no help, I thought of reverting to the Internet for my questions. Hoping to answer and ask many questions. :)

I am an enthusiastic learner!

Hi, I have just joined Physics Forums, I graduated in chemistry in the UK back in 2003, although I am interested in all scientific disciplines and like to expand my knowledge. I work in the oil industry, and frequently have to call upon physics and mathematical knowledge in order to perform...

I am currently a grade 10th student stuying in Germany. I was never interested in science subjects such as Math, Physics or Chemistry, until I heard about Einstein's theories and the book " A brief history of time" by Stephen Hawking. Now I have a totally different view about those subjects I...

Hello everyone :) Been reading your forum for a couple of years as a visitor and decided to take this opportunity to thank everbody for there exceptional intellect and insights. I have been a science fan since a child, but lack the formal education to pursue such vocations. Most of my knowledge...

My name is Tongyu Chen, and you can call me Creek. I'm a 21 year-old boy in physics and come from China. I am the only child in my family so sometimes I feel a little lonely. I play table tennis, volleyball and basketball. Though I looks not very tall I often get rebounding balls in basketball...

Hello everyone this is my first post on PhysicsForums I am in my second year of electronic systems engineering degree and I have to choose a final year project. I am really enjoying the modules on RF engineering and electromagnetics, especially electromagnetics is just too interesting I...

Well, I have become interested in physics and its relationship to philosophy and the mystery of the human conscienceness. I am 17 years old and love to learn new things for myself. I am becoming quite the self-educator lately and I am beginning to learn more about math and science than I ever...

Hello to everyone! I've just signed up after finding your site whilst trawling google for some answers. My name is Steve, and I'm from Leicester, England. I am 27 Years old, and very interested in some of the discussions going on here (and I hope to participate in some of them without...

Hello everyone, first time post here. Before the question, a brief background: Intro: My name is Brian and I am a flight instructor with a BS in aviation flight operations. I enjoy science in general and study it on my own time for fun. That said, my science background is still meager so be...

Hello everyone, this is my first problem dealing with Kirchoffs Rule and I thought I did it right...here is the circuit... http://www.webassign.net/hrw/hrw7_27-40.gif the info is the following: In Figure 27-40, the resistances are R1 = 1 , R2 = 2.2 , and the ideal batteries have emfs E1 = 2.0...

I'm very new to this. I know that to find the angle between two vectors we use the dot product, but what about finding the angle between a vector and each of it's axes? for example: A = 3i+2j+k, How can I employ the dot product when there is no other vector? Thanks and keep posting! Amil

Wellcome to PF spacecowboy. regards marlon
