Light and Dark 1 of 2 - Light

[@ericartman0]

I watch everything I can find Mr. Al-Khalili does. He never disappoints.

[@hodgymac]

Ditto he is great - as is Brian Greene too

[@hodgymac]

sure write a paper - and claim your Nobel Prize - that's how science is done

[@Darthenator]

@Joe Chang You bring up some good points. I do not understand all higher mathematics of it but have studied theory extensively. I agree the atomic model is BS, the inability to have a better concept bothers me greatly haha. Have been curious for some time how atomic model properly explains transference of force in matter. I would argue that time dilation due to relativity is essentially real world time travel if not the traditional notion of it. We still have not split an electron, which I gleefully look forward to seeing in the future, as it is the only aspect of the general atomic model we have not split and is still highly mysterious despite our widespread and complex use of them. It is strange to me that knowledge of the true nature of a thing is not the same as functional knowledge of a thing. As for the light in a vacuum deal, I am still scratching my head over that, I suppose the community at large is as well (unless I've missed something which is a near surety) what with the whole Dark Matter issue

[@josephma9037]

me too,his talking is interesting.

[@areebapirzada4714]

@Joe Chang Sir can you explain what time is actually?

[@MrBoybergs]

Jim is definitely the finest 'presenter' of science on TV (obviously only one small element of his skills and talents). He provides a relaxed, effortless and totally engaging experience when describing what would otherwise be very tricky concepts for the layman to grasp. And he seems like a bloody nice bloke.

[@markfourtwenty9897]

Well said...Even laymen will learn Quantum Physics by just watching his documentaries...

[@dreamoftheendless7159]

I love his documentaries

[@BillAnt]

He definitely keeps it interesting and comprehandable even by common people.

[@measydoesit289]

100% agreed 👍🏻

[@frankdimeglio8216]

He's political. He's indoctrinated. He's not acknowledging any of the following. THE THEORETICAL, BALANCED, TOP DOWN, ULTIMATE, AND CLEAR PROOF THAT E=MC2 IS F=MA ON BALANCE, AS ELECTROMAGNETISM/energy is gravity: Consider the man who IS standing on what is the Earth/ground. Touch AND feeling BLEND, AS ELECTROMAGNETISM/energy is gravity. The Earth is blue, AND the sky is blue. SO, overlay THE EYE in BALANCED RELATION to/WITH what is the Earth ! (The BLUE SKY is ALSO translucent !) GREAT. Objects fall at the SAME RATE (neglecting air resistance, of course), AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. NOW, we proceed to the next step. The stars AND PLANETS are POINTS in the night sky. Invisible AND VISIBLE SPACE in fundamental equilibrium and BALANCE IS the MIDDLE DISTANCE in/of SPACE in fundamental RELATION to the universal fact that E=mc2 is F=ma. The Earth (A PLANET) involves BALANCED electromagnetic/gravitational force/ENERGY, AS E=MC2 IS F=MA. The Earth AND the Sun are CLEARLY E=mc2 AND F=ma IN BALANCE pursuant to what is the BALANCED MIDDLE DISTANCE in/of SPACE !!! Consider what is the speed of light (c), AND consider WHAT IS THE SUN. NOW, think about what is the Earth. Importantly, outer "space" involves full inertia; AND it is fully invisible AND black ! Great. Accordingly, the Earth is in BALANCE with what is the Sun, AS the orange Sun represents what is LAVA ON BALANCE !!! Great. (Notice the role and relation of what is the EYElid.) The MIDDLE DISTANCE in/of SPACE is universally balanced to/with what is THE SUN AND the speed of light (c), AS E=MC2 IS F=MA !!! Gravity IS ELECTROMAGNETISM/energy. Notice the black space of WHAT IS THE EYE, as the stars AND PLANETS are POINTS in the night sky IN BALANCED RELATION to/WITH what is the MIDDLE DISTANCE in/of SPACE; AS E=MC2 IS F=MA !!! The FULL DISTANCE in/of SPACE is truly linked AND BALANCED to/with what is THE MIDDLE DISTANCE in/of SPACE, AS E=mc2 IS F=ma IN BALANCE !!!; AS ELECTROMAGNETISM/energy is gravity !!!!!! GREAT !!!! Notice that the viscosity of lava IS BETWEEN that of WATER AND the Earth/ground ! The orange Sun is the same size as THE EYE. Outstanding. E=mc2 IS F=ma as what is the BALANCED MIDDLE DISTANCE in/of SPACE !!!! GREAT !!! LOOK at the progression AND THE BALANCE regarding FULL DISTANCE in/of SPACE, MIDDLE DISTANCE in/of SPACE !!!, AND A POINT (ALSO c) !!! E=mc2 IS F=ma !!!, AS ELECTROMAGNETISM/energy is gravity ON BALANCE !!! GREAT !!! It ALL CLEARLY makes perfect sense. BALANCE AND completeness go hand in hand. E=mc2 is F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity !!! Gravity IS ELECTROMAGNETISM/energy ON BALANCE !!! TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS E=mc2 is F=ma; AS ELECTROMAGNETISM/energy is gravity. INDEED, TIME DILATION ultimately proves ON BALANCE that ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=ma !!!! INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, AS E=MC2 IS F=MA ON BALANCE !!!; AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!! GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=MA; AS ELECTROMAGNETISM/energy is gravity. Accordingly, the rotation of WHAT IS THE MOON matches it's revolution !!! Notice what is the fully illuminated (AND setting) Moon in DIRECT comparison with what is the orange Sun !!! Again, the stars AND PLANETS are POINTS in the night sky. A given PLANET (including WHAT IS THE EARTH) sweeps out EQUAL AREAS in equal times consistent WITH/AS F=ma, E=mc2, AND what is perpetual motion, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=MA ON BALANCE !!!!!! GREAT. Gravity IS ELECTROMAGNETISM/energy, AS E=MC2 IS F=ma !!! By Frank DiMeglio

[@LiViro1]

He obviously has writers and a crew, but still I think this presenter is a genius. Really one of the best documentary makers around.

[@NomadUniverse]

Prof. Jim Al-Khalili, he wouldn't have to have written much. I wouldn't be surprised if he wrote most of it himself.

[@robertgoss4842]

Dr. Al-Khalili has no peer in his ability to present complex ideas to us ordinary mortals. I'm an average Joe with only a fragile grip on just the bare basics of physics, but I am riveted by these videos.

[@homersamson2635]

Al-Khalili is an outstanding science communicator. His passion to understand the universe is infectious and inspirational. Credit too, to his production team. This is an excellent video.

[@mike814031]

I love his videos, they are one of a kind. no one else explains and narrates quite as well as he does. hands down one of the best I've ever seen

[@nateellenberger6043]

That was the most AMAZING example/explanation on how lenses bend light to magnify an object (scope). It hit me hardcore! :) Jim is a badass dude. (10:24)

[@nateellenberger6043]

Jim always makes these documentaries that much more interesting. Entropy (Order and Disorder) is another mind blowing documentary with Jim Al-Khalili.

Thank you so much Sir, for putting this doc on KZbin - I've been searching for YEARS to find it...I'm studying physics and remember this when it was first broadcast as being a great doc i always wanted to come back to

[@jen3800]

brilliant presenter and presentation!!! this makes my little heart beat faster. genius.

[@jeankelly8943]

Magnificent lecturer... it's obvious he mastered the matter so profoundly he has that special ability to gorgeously simplify explanations of the hardest stuff in science

[@seemitbharti3632]

I envy kids of today. They have so many resources to learn from. Jim is a great story teller, communicator, presenter and teacher. These videos should replace some classes in schools today. I could have learned so much more in the time I spent going to libraries and "books surfing". But at the same time, I know future generations will find life elsewhere faster than we expected a decade ago.

[@rugosetexture2716]

Dr. Al-Khalili is always a favourite! Thank you very much for making this available.

[@briank1263]

I've found myself watching nothing but facts about the natural world. A pursuit of knowledge I've never felt before.

[@jsmcguireIII]

Really liked this two-part documentary. Jim Al-Khalili chose to focus on some of the more obscure but essential players - and beautifully omitted the names of those more powerful and famous players who were slow to admit their mistakes. I also liked the production style. He would just stroll into the control rooms of these amazing observatories and recreate the findings made by earlier researchers. His hand calculations of some of the key formulae was a cool contrast to the technology. I wish he had been one of my professor.

[@innertubez]

Jim Al-Khalili is a fantastic science show host. Reminds me a little of the gravitas and sense of wonder that Carl Sagan had.

[@jenko701]

Anything he does is golden .

[@MeissnerEffect]

Eric Hamm one thing I love about being a huge science fan! The sites I visit and videos I watch about, say - astrophysics by Fermilab, have comments below that just discuss the topic, share ideas, and even support other commenters on how to find out more. No one cares about race, creed or anything else on most occasions. I'm so sick, in these horrid and divided times of the hideous, hurtful hate-speech, bullying etc. I just avoided all comments and felt better for it. It shows me something also, that those interested in science are in general nice folks. Have a great day, and enjoy your growing wisdom from watching the amazing Jim!

[@gkarthikraja3593]

Those who do bad things are bad people, that's it. Isolate the religion term from it. Religion is not the cause, ignorance is. So keep learning and don't be ignorant.

[@FredHandle1]

Khalili is an old spirit diving into the ways of nature. He is not a geek at all, rather he ventures in as a Philosopher-Poet a spirit attempting science. In his narrations we relive the quest of the many great minds from the vantage point of a Sindbad on his carpet. His mind does not scream through the discoveries, rather it relives the constriction of its frustrations & the wonder & implications of its opening. If this is geeky to you, then life will quickly become boring for you bc you're just executing life & not consciously living its drama.

@45:12 he make the case for Maxwell's equations and @47:05, he says that "if you work that out...", the square root of mu naught and epsilon naught, "...you arrive at three times ten to the power of eight meters per second.". But, there must be values plugged in that give that answer. It's like e=mc^2. People are always asking for what values to use for e and ma and c. and, the answers are always mixed. It's dimensionless. Use SI units. Just accept it as it is. And, on rare occasions, "I don't know". I don't believe that light HAS to be an electromagnetic wave. In fact, it seems absurd that an electromagnetic wave would have no discernable interaction while passing through either electric or magnetic fields. But, I suppose, to a mathematician, such nit picking is just that. Something to be ignored. And, it is. @48:58 he says that since light is electromagnetic waves it doesn't need anything to travel through "empty space". But, space is not empty. It's teeming with 'stuff' (at the risk of angering those who paid careful attention in science classes and dutifully memorized the lessons, I'll call it 'the aether'). Stuff that acts as the propagating medium for light (and light-speed phenomena).
