- Einstein’s theory of special relativity is one of the fascinating scientific advances of the 20th century. Fermilab’s Dr. Don Lincoln has decided to make a series of videos describing this amazing idea. In this video, he lays out what relativity is all about… what is the entire point. And it’s not what you think. It’s not about clocks moving slower and objects shrinking. It’s about… well, you’ll have to watch to see.

Does this work if i get a speed ticket? I can just say "No officer, you were moving"
Substitute your velocity in the equation and claim that the police officer was moving with that speed
Both - you and the officer get a ticket!
@@kimsahl8555 Yes you are right
You can try, but be prepared to be accosted by an egomaniac
@Nova Brody seems a scam lol
You present the material in a clear fashion while not talking down to people that have very little background. Thank you
When he gives you "a second to take that in" - he really gives you ONE second
LITERALLY 1 SEC... TO SINK THE FUCK IN
Well, from a different perspective he gave like 10 minutes

This idea is great. I would love to see separate series on Relativity, Particle Physics - Standard Model - Particle Detectors. Keep up the good work!
One on Quantum Mechanics would also be great!
@@davidrowe762 THE CLEAR, INTEGRATED, EXTENSIVE, LOGICAL, BALANCED, AND MATHEMATICAL PROOF THAT ELECTROMAGNETISM/energy is gravity:
Consider what is E=MC2. TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. The MIDDLE DISTANCE in/of SPACE AND the full distance in/of SPACE are CLEARLY linked AND BALANCED opposites (ON BALANCE), AS c squared CLEARLY represents a dimension of SPACE (ON BALANCE); AS the stars AND PLANETS are POINTS in the night sky ON BALANCE. This CLEARLY explains and proves TIME dilation AND what is the fourth dimension. CLEARLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites (ON BALANCE); AS the stars AND PLANETS are POINTS in the night sky; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). Notice what is the TRANSLUCENT blue sky ON BALANCE in relation to what is THE EYE. What are OBJECTS may fall at the SAME RATE in order to VANISH as part of what is THE EARTH/ground (ON BALANCE). TIME dilation CLEARLY proves that what is E=MC2 is CLEARLY in FULL accordance with TIME AND the fact that ELECTROMAGNETISM/energy is gravity, AS the stars AND PLANETS are POINTS in the night sky ON BALANCE. (Indeed, TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE). Notice what is the orange (AND SETTING) SUN in what constitutes direct comparison WITH what is the FULLY ILLUMINATED (AND SETTING WHITE) MOON. (They are the SAME SIZE as what is THE EYE, AS the rotation of WHAT IS THE MOON then matches it's revolution; AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH what is E=MC2, TIME, AND what is THE EYE ON BALANCE.) Consider what is the man (AND THE EYE ON BALANCE) who IS standing on what is THE EARTH/ground. TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. LOOK directly overhead at what is the BLUE AND TRANSLUCENT sky. (Consider what is invisible AND VISIBLE SPACE in fundamental equilibrium AND BALANCE.) NOW, lava is orange; AND it is even blood red. Excellent. ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE) pursuant to what are E=MC2 AND TIME. Accordingly, ON BALANCE, the rotation of WHAT IS THE MOON matches it's revolution; AND the cosmological redshift proves that ELECTROMAGNETISM/energy is gravity; AS the stars AND PLANETS are POINTS in the night sky ON BALANCE. (Consider TIME AND TIME dilation ON BALANCE, AS E=MC2 is taken directly from F=ma; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity ON/IN BALANCE). INDEED, GRAVITATIONAL force/ENERGY is proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE; AND “mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY; AND gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH E=MC2 AND TIME. This CLEARLY explains and proves what is the fourth dimension. I have also CLEARLY explained (ON BALANCE) why THE PLANETS move away very, very, very, very slightly in relation to WHAT IS THE SUN, AND I have CLEARLY explained ON BALANCE why the rotation of WHAT IS THE MOON matches it's revolution. ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). (BALANCE AND completeness go hand in hand.) Excellent. The INTEGRATED EXTENSIVENESS of THOUGHT AND description is improved in the truly superior mind. Again, consider what is the BALANCED MIDDLE DISTANCE in/of SPACE (ON BALANCE) in accordance WITH WHAT IS E=MC2 AND TIME; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE); AS c squared CLEARLY represents a dimension of SPACE ON BALANCE !!! Indeed, now consider what is THE EYE. It ALL CLEARLY makes perfect sense ON BALANCE. Magnificent !!!

I would like this format and would like to see you expand it to other subjects as well. Thanks for helping us understand the works around us.
I’m binge watching the videos of this channel, everything very well explained, complex concepts enlightened, great dynamic!!
This might be the most comprehensive in-depth physics channel on youtube! you guys rock!
Don, this is great. I'm building up to a deep dive in special relativity, but it's a ways off at this point and these videos will be a nice primer to set the stage for that. Thanks for looking over the comments and trying to put together something that your viewers are looking for. It's greatly appreciated.
Yes, please, make more of these in a series. Demystification of Special Relativity would be most welcome.
Series of connected videos are great I hope you can make series like this one also for quantum mechanics string theory QFT QCD......big fan btw
I love the idea of connected, educational physics videos. Please, keep it up! :) I look forward to the next one.
I really like the way this guy muddles the info nicely. Thanks
You are the best (imho)
Thanks for keeping up the good work.
This idea of serialised videos is awesome. Hope more from FERMILAB
Great video, Don; love the idea of a series covering a single topic. Gives an opportunity to dive a little deeper on these ideas!
@Keylanos Lokj - interesting that you say Einstein's equation "was stolen by DePretto who published it three years earlier." ... He must have really got the hang of all this spacetime malarky.
Hey jon watching don
I am loving it, professor. Connected videos make possible to explain a subject clearly and completely but in a good rhythm. Also, adding math to the explanations is great and necessary.
I would love stuff series like this about particle physics.
Thank you so much
I was never good at physics in high school, but watching these videos has helped me understand principles that I didn't understand as a kid. Thanks!
It is great to see Dr. Lincoln explain with such a detail how relativiy works in a fundamental way. I'd love to see this kind of videos.
Appreciate a longer take on special relativity. Excited to see more of the series!
Thanks, Don! Oh, where were you when I was in high school physics! The idea of a linked sequence developing ideas one central point at a time is excellent. Then understanding unfolds like a spring flower ... exuberantly!
anything you do in any format is the best. Your fans will watch whatever you publish.
Love the idea of connected videos. Do not limit the format to just this subject.
Love the 4k format, thank you.
Your great precise enough for proffesionals and yet you explain the basic concepts in an easy enough way for the layman (guy on the street) great work .. It's always hardest to explain something so everybody can understand...
Great channel man 👍. Loving long playlist. Subscribed
Dr. Lincoln, OF course we love to see video series. I personally wouldn't even mind if you bring about super hard equations as well (I can work the math).
Love the idea of connected series. Please continue, I'm a big fan.
All what you do is great! I love the idea of a series of connected, detailed, videos
Excellent video ! WOuld love to see videos in series, it helps me understand better the patterns.
Fantastic! Dr. Lincoln i really appreciate your explanations of physics topics. I like the new intro very much. Now that I'm retired as a physician i can study physics for fun. They are spelled similarly, any way.
Please continue this series!
Love the new format :) more please !
You ROCK Dr. L!!!! Keep em coming! Love the new format, but the previous ones are grrrreat too! ~peace
As an Electrical Engineer, I wanted to say that your videos are just as entertaining to someone experienced with these concepts as they are to a layman. :)
you just wanted everyone to know you are an Electrical Engineer
So what the fact is he's an electrical engineer and you're not
@@johanan9987 wrrrrooong!
@@mrld3005 you just wanted me to know you're an electrical engineer ;) and I guess we are all electrical engineers
@@johanan9987 hahahah
Great idea, Dr Don! I'm really looking forward to this series! Thanks!
Finally! Longed for a series for better clarity.
This is the series we've all been waiting for. Thank you Professor Don!
Series videos are a great idea. How about a video on identical particles. It seems unbelievable how electrons can be identical including their charge.
Thanks Don for your enthusiasm and ability to convey relativity to all observers!
Looking forward to the next installment!!
I love the idea of doing a series on a single topic and I'm excited to see you do it! One thing that I've been thinking about with the second assumption (that the speed of light is the same in any inertial reference frame) is that it should follow from the first assumption. Since the speed of light is a result of two fundamental constants (vacuum permittivity and permeability) and the first assumption is that the laws of physics should hold in any frame, the speed of light follows naturally and doesn't have to be taken as an assumption. I've seen people ask why the second assumption should be valid in the comments a decent bit and think that, though getting to the speed of light through those constants is not particularly intuitive, it does provide a solid basis for the assumption that the speed of light should be the same in any inertial reference frame.
Would constants being frame-independent not be implicit in the assumption that the laws of physics are frame-independent?
To be clear, I don't disagree that the fact that the constants really are constant is, in fact, amazing. I'm just arguing that it's already baked into the assumption that the laws of physics are frame-independent.
Awesome! I think the idea of short series of videos is an great idea.
Great videos. A playlist, in a logical order, for all the "special relativity" videos would be great. Then go back to the descriptions in each of these videos and put a link to the playlist.
Thank you so much for explaining the core meaning of Special Relativity. Now, have you done a video explaining the Andromeda Paradox? I cannot seem to wrap my head around it and would appreciate your help.
Dr. Don is a brilliant presenter and professor! Someone who really knows the subject matter, which is reflected in the way he presents it: as simple as possible, but not simpler!
Great explanation! I would love to see more series! Above all, I would love to see Don explaining Delayed Choice Quantum Eraser! I've never watched a good explanation that didn't used retrocausality! =)
Thank you sir for the exceptional clarity in your explanation. Love this mini-series on special relativity. I am relearning what I have learned in college two decades ago.
Love it. Series sounds like a good idea
Any subject you choose is great to me. I love it all. You do it and I will watch it and study it.
Yes Dr Don - the series approach is fantastic. Love your work!
Dr Lincoln, your videos and Fermi Lab rock. I do appreciate your efforts. I’m so glad DOE supports your educational outreach. Physics is everything. I worked in Oak Ridge for 38 years. I believe in our national laboratories. Thank you.
I can't wait for the next video. I like all of Dr. Lincoln's videos. Thanks Doctor Don.
Yes, series are totally acceptable. However, your rollout date (we'll call that T=It'sOn) intersects with MinutePhysics rollout of their newly announced series on Relativity. Accordingly, that transforms into an old fashion throwdown as represented by the equation FL>MP? The derivation of that equation is content dependent. This should be good.
I'm looking foward for the next video!!!
Nice video Don. Could you explain what is happening with gravity on a quantum level and what the equations are? Or at least best hypotheses for quantum gravity?
Dude, you are awesome!! I’m a hack lacking proper background, and your demonstrations have made my reading knowledge make much more sense! Thank you!!
Awesome videos, thank you so much for these concepts so easy to understand. Great work
Excellent idea to start a series on Relativity. THANK YOU for this and all your Fermilab videos. You just might teach a former Aeronautical engineer to understand Einstein Relativity.
Definitely like the new series format..
Thanks for your hard work and being a good teacher. Looking forward to a series of linked videos.
I like your idea to make a coherent stream of video. You explain the theories well.
First, thanks for doing a series on this!
And that's why Relativity is often explained with trains. You can do the explanation with a passenger on a train without having to think "Man, the car guy is crazy. He thinks he's not moving? How can he drive like that? He's a danger to everyone on the road!"
A nitpick of course. Good video, Don!
You are a great teacher. Thank you and all your team.
I loved it so much!
I'm looking forward to understanding how these formulas are obtained.
Fantastic. Thanks a lot for the series of videos.
You are the best Dr Lincoln!
Please continue this series..!!
Great idea! more please!
Please connect videos that fit together for whatever reason. If you feel like explaining, fine. If not, that is fine also. Either way, I thoroughly enjoy the videos. topics, and the presentation. Thank You! so very much.
I do like this idea of a series of connected vids!! You might be covering this in a future video, but I thought I'd mention these Lorentz equations essentially reduce to Galilean tranformations when 'v' is very small compared to c. To me, this is really cool aspect.
I just love the idea of making series of videos! Can't wait for the next episodes :)
I like your channel
You explain a complex topic in a very simple way
I loved this video. Thank you. Please continue the series of connected videos.
This an extremely nice way to teach beginners. Although I have read relativity myself, you doing great job for lots of beginners. This is only way to motivate interest.
Love the idea. The World Science Festival channel recently uploaded multi-part videos and they were well organised, easy to follow. Best of all: you can really get a deeper understanding of a topic. I'm ready to go deeper ;)
Great idea to make a series. But there should be a clear list of which videos make up this series. I want to see the series, but I have to choose the videos about relativity rather random or guess which is next.
I love your work so much
Love it, looking forward to the next videos!
For strange reasons I can't hear your audio, but any other video on this same page works perfectly. Perhaps my ultrasound abilities are already matching your skills?
I love this format!
Love these! Thank you!
This is helping my A level Physics students (18 years old) here in the UK - thanks so much. Connected videos is a great idea.
Awesome series.
I love all of what you do. Do it's anyway. You are the best teacher ever.
Oh, wow, this was so educational. I always wanted a concise explanation that doesn't assume i already know stuff. Gonna give it to my dad, bet he'll love it.
I really liked the idea. Thanks for the hard work for making these videos.
Love it, bring on more formulas !
Can you touch upon tensor mathematics too ?
Sir you are the greatest explainer I have ever seen
I've learned more physics from this channel than in school. Excellent work.
Great explanations
Very good explanation Dr. Don, thanks for doing this. The gamma part of the equation interests me.
This is a GREAT idea.
You combined the key concepts and explained how they relate to the key equations by using every day situation/language.
I find it AWESOME to have more mathematics incorporated so that I can understand the LOGIC behind their derivation along with their significance in the grand scheme of Physics.
I also like the new jingle/intro and I will definitely be looking forward to subsequent videos! :)
Thank you so much Dr. Lincoln
Great!! Loved it professor.
Your videos are the best,keep up the good work!
I like the idea of a series of connected videos. It's absolutely great...well relatively great.
Can i know that, have u made any video regarding 4th dimension...if u haven't made it ,could u make it....please
Great job, Don! The series is an awesome idea!
yes. keep the series format.
