I'm glad I found it.

Ok, well, firstly I'd like to say hello to ya'll and thank you for letting me join. A little(maybe not so little in appearance) about me: . I'm a analytical flesh bag full of curiosity and fortunately enough mental ability to sometimes be referred to as "smart", but that is depending on the...

I'm excited to be here!

Hope to get a bunch of my doubts cleared. thankyou

I'm glad to join this community.:blushing:

I like the structured approach PF uses in the explanation and study of physics.

Hello just joined Name's precious

HEllO please I love you

I'm out here

Hello everyone, I am a layman who basically cannot do math, yet am inexplicably drawn to physics and chemistry, so here I am to learn and ask questions, mostly! I don't know what else to say but nice to meet you all!

Hello ! We all now that enzymes lower the activation energy by creating both covalent bonds and week non covalent bonds , in this book , about how the enzyme lower the activation energy using covalent bonds they said : this sentence is not compatible with a basic principle that i learned in...

These are the photos you're looking for! The first proper batch of photos from the soon-to-be-released Kenobi series have arrived. Here are a few: In this one he's perched on a bit of high ground inside an eerie-looking cave. Could he speaking to the ghost of Qui-Gon Jinn (out of frame)...

Hi everyone, I'm in my 30s and I realized through reading that I'm interested in Physics. I grew up poor, so I went to a poorly funded school. Surprisingly, I didn't learn much because my teachers were too stressed out managing a bunch of rowdy kids (/s). Anyway, I didn't learn much physics, or...

Hi everyone! I’ve just discovered Freud‘s theory's, how fascinating! I was searching the web for information on narcissism and stumbled across this. I’ve got a lot of issues from my childhood and have had little help from the mental health sector, not for the lack of trying. I truly believe we...

Hello. Be v grateful any assistance with this. Question is energy to haul 2000kg 4 metres up a 1 in 100 incline with 300 Newtons friction Answer is given as exactly 1.98 kJ. The only figures I can see that relate to anything here are 2000kg minus 10 = 1980, and 1:100 is 0.01 which times...

Hello all, Here's the deal. It's weird, but it's true. I will swear on "The Precious" if necessary. (gratuitous Ring reference) Due to the unique circumstances surrounding my life, I have lived in a major depressive with borderline personality traits state for the better part of 40 years...

Hello, I am new to this forum. I have a question, hope I'll find some answers here. My question is - if there are 2 fishing rod, one lighter (physical weight) than the other. Will the lighter fishing rod cast a lure/bait further than the heavier fishing rod, assuming the rod length...

Dear all, I am new to this forum and I am looking forward to having revealing discussions with you on here. My name is Thomas, I am 25 years old and currently writing my master thesis 'Parton Density Functions for Heavy Gauge Bosons and the Higgs' at DESY Hamburg. My field of interest is...

Yahallo~ Call me Tasukaki :w. I'm a high schooler that is fascinated by Quantum Physics and Mathematics.UwU Although I'm probably a Novice in these subjects compared to a Master, I'll be looking forward to asking the community tons of questions :D. See you around~~

Hello everyone! My name's Maxi and I'm a 16 years old high school student from Argentina. My dream is to become an aerospace engineer someday. Currently I'm researching for a science fair held by The Pierre Auger Observatory, which means I'll be around this amazing site asking some silly...

Hi, I’m Harper Chisari, a high school student from Pennsylvania. Officially, Ⅰ have only finished Electricity and Magnetism and Mechanics (at a high school level) and Multivariable Calculus, but Ⅰ have also studied Linear Algebea and Differential Equations through edx, as well as Intro to...

Hello, Definitely excited to be apart of this community. I hope to broaden my understanding of physics - both from the questions of the inquisitive and the answers the bold believe to hold true.

Hello! I'm an aspiring physicist who came here to learn more about this wonderful area of study. I'm so happy to be here! :)

Hi, can somebody tell me how to connect some component in this picture, i draw it but is not working because i have no bfg520 transistor, look this picture maybe i make mistake

Hello, Can somebody help, to understand the transistor, what does do 390pF and C(tune), and 4,3µH, they form tank circiuits? and also resistor 1K and capacitor .1, is possible somebody with little words to descirbe how it works please... Thanks.

Hello there. In all honesty I am college dropout, but have had a bit of an obsession with quantum physics for the last year or so. I look forward to learning from everyone and maybe sharing what I understand of the basics and see what I need to learn.

Hello everyone, I began using this for help with some concept homework questions for my physics 1 course. I dream of getting a PhD someday and focussing on astrophysics. I would want to work near the west coast so I could take advantage of their clear night sky. I'm only about 60 credits into my...

Hello, I'm just an undergraduate student in their final year at university. I've never been good at mathematics so I want to pursue it as a hobby and a challenge to myself, starting from the basics! I have a few questions of my own floating in my head so you'll definitely see me sticking...

So... by the title I most say thay if I were to read this I'd think "This kid got lost", and I thought so too, but recently I've been having a lot of interest relating to simple science, but with a different focus (for example, parabolical movement, but applied with friction force, and how to...

Hi. So I’ve been teaching myself mathematics and physics, and over the past year I’ve been buying various textbooks. I’m currently reading Stewart’s “Calculus” (6th edition), “Elements of Set Theory” by Enderton, and “Number Systems and the Foundations of Analysis” by Mendelson, and I’ve been...

Well Hello Everyone :))

Hello everyone, I am a regular college student currently pursuing my Masters in Physics. I don't know how this forum works though? What the forum rules are etc.? I read something about the "No homework questions please" rule. Well, that's a bummer. (jk I hope we are allowed to make jokes?) I...

At School physics was perhaps my least favourite subject because it has quite a strong link to maths and I was bad at maths and couldn't get my head around it. Maths was my second least favourite because it mainly concerned itself with either pure numbers or someone called Billy wanting to know...
