Spahn's Science Lectures
Приєднався 6 чер 2016
Mr. Spahn was born and raised in South Milwaukee, WI before moving to Florida for an undergraduate education at Florida Tech. In 2013, he received his B.S. degree with a double major in astrophysics and mathematical sciences. Mr. Spahn then moved to Texas to pursue a masters degree in physics at Texas A&M University-Commerce, which he obtained in 2015. During this time, he also served as a teaching assistant, a research assistant, stockroom manager, and was the president of the Society of Physics Students chapter. In 2014, he was awarded an NSF STEM scholarship for his research of a cataclysmic variable star system and an AAPT outstanding physics teaching assistant award for his contributions in the classroom. Mr. Spahn joined the faculty at Southeastern Oklahoma State University in 2015 and now teaches courses in Physics 1, Physics 2, Astronomy, Earth Science, concepts in physics, and Physical Science, and has earned back-to-back excellence in teaching awards in both 2020 and 2021.

Channel Update: Lightboard and More!
Переглядів 307Рік тому
Over my winter break, I spent a lot of my time building a lightboard and setting up my home office for the primary purpose of creating videos both for my students and for this channel. This video begins with a tour of the new setup before showing you a sample of what it can do. This is all very new, and I still have some kinks to work out, but I am very excited to enter this new stage in conten...
January 4: Perihelion Day - The Day We are Closest to the Sun!

For question 3, how do the spheres remain charged despite the rod being removed?
I should of been following these lectures when i was 19. lol
This is very informative!
Science has always been an interest of mine, i tried Biology course in college which didn't work out. but now i'm totally interested in Astronomy and will be using these lectures to prepare for college. :) Thank you!
Thank you for explaining this
Hi! You are an amazing lecturer. You mentioned "if you have my actual course" how do I access this/purchase it?
trying again for retakes . İ NEVER SEEN YOUR CHANEL SPAHN SCİENCE BUT İ BELEİVE YOU AND KİNDA BELEİVE MYSELF
Anyone else get 60 cm and -30 cm for Q3? @31:13 Distance was ... 40 to 15, 15 to 30, 30 to 10 so... (40-15)+(30-15)+(30-10) = 60 Did I do the math wrong?
tyyyy this helped a lot
That nebula picture is actually the coolest image I've ever seen. It almost looks like the dark nebula is some kind of monster consuming the cosmos.
I'm an italian university student, and you managed to explain the basics of algebra in 30 minutes, while other teachers manage to do that in 8 lessons (if you're lucky). Keep up the good work, my friend <3
I am so thankful that I found your videos in time, I think you honestly saved me from my exam, your explanation is easy and straight forward to the topic related, whereas I see my professor tends to explain the topic in wayy to much details, and it becomes really redundant information that I don't need. Thank you so much :)
I hope all teachers are like you
I don’t understand why the lecture is called “College level “. Looks more like “O Level “
Bro this video is awesome. Thanks for it.
Awesome lecture
Thanks for sharing this content! At around 41:20, for #4, wouldn't the electric potential energy increase from point 'i' to point 'f'? At point 'i', both positives should be canceling each other out, leaving the electric potential energy at 0. At point 'f', if we do a vectors sum, the two positives should be pushing our positive test charge straight up, meaning it'll have some electric potential energy. So I think point 'f' would have a higher electric potential energy than point 'i'. Correct me if I'm reading it wrong!
I don't understand the table at around 22.41. Firstly, if the orange bars represent new temperature records shouldn't each be taller than the last? The first four, in 2009 and 2010 are successively taller, but the next orange bar is shorter. Secondly, what average is referred to , that all the differences are positive? If it's over the time period in the graph, some should be negative.
When you view something, how do you know if you're looking at a small object close up or a large object far away?
Is it me or is there an error with the units and calculation in example 28.1 at 23:24?
Thank you Sir.
Thank you Sir
Did you understand
thanks for your lectures
u
perfect lecture.❤❤❤🤓🧐
It was pretty good
thanks
i got a 31 on my first physics midterm and a 66 on my second one after mainly learning concepts through your videos. Thank you for the clear and thorough explanations! I appreciate how you connect the formulas through logic and explanation rather than just throwing them on the screen and not explaining why they are what they are.
Hello! Very instructive and informative lecture! However I have to point out that it needs a little refining. Others have pinpointed the poor analogy of the mass of a teespoon of neutron star material and cars... I have to mention that the earth's radius and not the diameter is about 6370000 m as mentioned at 52:37!
To me the last question's answer doesn't make any sense. How come the car is not falling or accelerating downwards if the net force is downwards and nothing is acting against it?!
Thank you!
I'm a Engineering major and about to take Intro to Physics. Thank you for this resource sincerely
on the car problem I did (1500 X 1.2) + 320 then divided it by cos(20) but got 2256. Did you round that up to 2300N?
in another physics class. basically just gave us the textbook to read. I appreciate your work so far. its great when a proffessor is passionate about teaching.
Hi Spahn, I'm working through the course, in the ramp problem here @27:00 would delta x be the adjacent side of the triangle not the 360m hypotenuse? or is this a tilted axis example? Thanks for all these videos BTW they're great.
You are literally the hero of physics
these were bunch of the best lectures l have ever had, simple and full of info,.. waiting on fire for physics 3. hope you explain it as you did for physics 1 and 2.. this helps alot.. god save you, sir
Loved the lectures. Thanks for uploading. It really helps with bad professors. lol
Thank you
Thank you
Thank you for these videos
Thank you so much
Dude, gonna give u my medals, u are so amazing teacher
is there anyway you can make a lesson focusing on the nyc regents, My daughter does not have a teacher and she feel's like she's going to fail,
Hello Professor Spahn, at 12:29, did you mean to write (-1.0x10^-9) instead of (1.0x10^-9)? Since its a negative charge instead of a positive one
no because its the absolute value of the charge
@boidlol ahh gotcha! Thank you!
You're a lifesaver dude
Thanks a lot for these really clear and well-illustrated explanations !
To you send med exam chapter 1,2,3
very few comments no way. man you did the best ever physics lecture yet not much reach.
What is he describing

Thank you for sharing this knowledge with us ❤🎉❤
That was a very detailed and great lecture. Thank you so much!
