"Understanding the retrograde motion of Mars didn't come easy, that's why it took over 2000 years to work out.. But i'm gonna explain it using a stick and some rocks.."
And he does it so well, that everyone can see!! Such a great communicator! :)
can you imagine explain with out sticks rocks
retrograde motions seem worth investigating further will do so
So interesting. I could listen to Brian talk all day.
Took 2000 years to understand it and now he explained it beautifully in 2 min
Recently watched his both shows and i gotta say that he is immensely dexterous on how to convey the info glibly. Kudos to ya professor brain
I loved this series with it's wonderful visuals and amazing locations, but for me it is this perfect, simple explaination that was the highlight. Nice one Brian.
Best explanation of retrograde I’ve come across. Brian is a wonderful teacher.
"Simple..." :-)
What an ingenious way of explaining it.
Superb Explanation!
I am searching this video for long time because I watched this video on discovery channal long time ago in Hindi. Then I can't understand this concept.
Now I am fully understand the reverse motion of Mars.
some really good stuff here
Really good way of explaining it, was very easy to understand =)
Thank you! i sort of understood it before, but this is what i needed.
Perfect.. what a great youtube 'find'.!!
Interesting link! You're right - the other models show retrograde motion, but I wouldn't say they're exactly the same one. In each model, the planets end up in different positions relative to the constellations.
Perhaps it would be better to say that the retrograde motion in the Copernican model fits actual observation more closely than the Ptolemaic model.
Johannes Kepler took almost his entire life to discover this and write down the laws of Kepler
This helped a lot! Fanks!
Science.
wow. he's just so amazing, im literally in love with him...
ahh i remember this from my astronomy lessons !
:)
So very cool
Well explained :)
thats soooo cool
love the video really good
OMG i learned something so cool!!!! o.o
Where does the up curvature loop come from? When you pass the other vehicle and it appears to be going backwards, it’s still in a straight line. The vehicle doesn’t loop upwards.
Perhaps the orbits of the planets aren’t perfectly in the same plane, and are instead slightly tilted. Unlike two cars on a flat road
earth would pass mars then would go back.
that loop happens only once. till earth surpasses again.
and will be behind again.
so motion goes from forward.
then backward when earth surpasses.
then forward again when goes comes around.
"I'm gonna explain it using a stick, and some rocks... then I'm gonna use the stick, the rocks, and some bubble-gum to build a helicopter and escape".
He changed sticks, I call fake. He also cleaned up after he broke the stick on the first cross. I call mega fake (Joking)
I never knew that!
This is Cold Hard Logic
@77GSlinger In modern calculations, the origin and orientation of a coordinate system often are selected for practical reasons, and in such systems the origin in the center of mass of the Earth, of the Earth-Moon system, of the Sun, of the Sun plus the major planets, or of the entire solar system can be selected. HOWEVER, such selection of "heliocentric" coordinates has only practical implications and not physical ones. I will let you find the correct terminology using "quackamedia"! OWNED!
So can we conclude that there is no such thing as retrogration if we are keeping sun as the centre of the solar system but viewing this strange behavior as we are seeing it from earth,....
where to watch the complete episode?

simple.
But it's not that simple really. Why a loop rather than moving along a straight line? I guess it's because Earth's and Mars's orbits lie in different planes.
I can see Brian is desparetly fighting off female admirers esp from his rock n roll days so what better way to do it, have a JOHN NOAKES haido
u just mentioned constellation I thought you didnt believe in astrolagy Brian
thanks kinda like saying "you mentioned Mars Brian, I didn't think you believed in the Greek Gods'.
Are you trying to be funny or are you really this dumb?
You're conflating things.
retrograde motion.
People of flat earth society are partying now due to the flat earth you've taken
I don't buy it. Just because you say it's an optical illusion, don't make it so.
Where in the video was the word "illusion" mentioned? Besides, this apparent change in direction is explained by the heliocentric model; in fact, it can be predicted by this same model.
Uhm, am I the only one who thinks that this explanation was not that clear and evident at all? No wonder that scientific illiterate people still claim things like "the universe revolves around Earth".
+whiterottenrabbit Watch again.. maybe u didn't pay much attention. It's not that difficult.
DouglasLC
What? I didn't pay attention to your needless comment...
+whiterottenrabbit I see what you mean, a little bit more explanation would not have hurt - in the last part after Earth has passed Mars and continues to move ahead in the cycle it has a smaller component of velocity in the plane in which Mars is moving - so on the 2D projection it appears to catch up. Imagine over taking a bicycle just before a cross roads, you turn left, the bicycle goes straight on - if you view this from the perspective with your car coming towards the observer it appears that the car first overtakes the bicycle then it stops and the bicycle then overtakes it.
+whiterottenrabbit Made 100% sense to me

Good for you. Now, go away and play!
