[@aloosi]

crazy how he managed to lip-sync it in reverse

[@RSPikachuAlpha]

Aloosi - Lilj0unior it’s not lip-syncing. He sang it reverse

[@ysvleis]

No, he only learned to sing it in reverse for the video, in order to lip-sync to the recording which was made normally. Still doesn't mean it isn't amazing, which it is.

[@Merr134]

Once upon a time when Tim was, maybe 11, he got his first sound recording program on our out-of-date computer. One of his first multi-track projects was to record the song "Barbara Ann" in adorable, pre-pubescent 4-part harmony. Tim used his sound program to flip the song backwards, then listened to it enough times that he learned to SING it backwards. It sounded so funny that it became sort of a party trick - "Tim, sing Barbara Ann backwards!" For some reason Tim found that annoying, and before long he had sworn off backwards singing and would snap if we so much as mentioned it. But you know, they say nothing you learn is wasted. #OriginStories

[@waynezeller]

Astonishing. Watching it I coudn't figure out how you were syncing the mouth movements. Surely, I knew, you weren't actually singing it backwards. And then I watched the making of video. Holy crap! You're singing it backwards!!!!! This is your most impressive video yet. And that's saying something because several of your videos have been really, really impressive. And congratulations on your impending TV appearance! Tell us more about that!

[@YesthisisCharlie]

He did sing it backwards

[@00GHY00]

Yeah.. that's so tough n confusing.. hats off to him

[@aniksamiurrahman6365]

But I don't get it. Played backward, talking backward will always have some kind of small choking noise. You can hear it in "Hi musical scientist" said in the end. But it's not present in the song. How did he do that? No matter how you talk, you can't make air go backward.

[@sandybullman2315]

Next time my mom tells me my room is messy I'll tell her : "blame it on the entropic time." Best excuse ever

[@jameson1239]

Blame it on a fundamental law of thermodynamics

[@RuchiraDatta]

When he sang that, it was close to the end of making the video and thus of making a huge mess in many ways. Blame it on *the making* of "Entropic Time"! 😂

[@LisaLiel]

Damn. The amount of effort he must have put in to lip sync that backwards is amazing. But there was almost an "uncanny valley" thing going on with his eyes, probably because of how hard he must have been focusing.

[@acapellascience]

+Lisa Liel It was the result of secretly having to look to the side to read nonsense syllables. I knew someone would notice... working on a fix for future projects because that really annoyed me too.

[@LisaLiel]

+acapellascience But other than that, it was freaking amazing. Kudos.

[@benf6165]

It reminds me of the Scientist by Coldplay

[@rakeshsimpson]

Are you serious? The moment I realised that you were somehow singing properly while playing backwards, my mind was blown away. Spend time thinking of all possible camera and editing tricks one could use to pull this off and was left scratching my head. You took the hard-work way! Kudos! Also, I love your videos :D Brings a smile to my face.

Why isn't this one on Spotify! This song is one of the best science parodies of all time, and the lecture that inspired it is sooooo good! I've watched that lecture more than I've gone to my actual classes this week!

[@Ruby-yn5fp]

maybe they didnt get the rights to publish a cover of billy joels song (the structure is identical)?

[@OrdinaryRobin]

I love this, loved it since I first saw it, but I only just noticed today that not only did you harmonize while singing backwards, you wrote lyrics that ended in syllables that matched their place in the original. There's not a word for this much talent. Even prodigy falls short.

[@SHOHOB2000]

dude keeps watching entropic time again and again and again never gets old it's too good to get old due to the effort put in it like shooting the whole song 5 times backwards while keeping his mouth movement reasonable just WOW

Hate to burst your bubble, but he wasn't singing backwards, just lip-syncing backwards.

[@Ruby-yn5fp]

@@matthewmitchell3457 still, the harmonies kill, like as a song he just nailed it first of all, let alone the backwards gimmick

[@anandsuralkar2947]

[@ARCISX]

Ikr It must have been damn hard..

[@JimmyEscajeda]

I think this may have gotten inspiration from Weird Al - Amish Paradise. I think he was the first to do this.

[@COMALiteJ]

@@JimmyEscajeda Yeah, but Weird Al only did it for like ¼ minute or so, and only one part. This guy did a whole song, five parts, doing all these stunts, each in a single continuous take.

[@TheRealBoof]

This is absolutely incredible. It's not obvious at first, but recognize the sheer amount of work that went into making this video! He filmed the entire video not just once but 5+ times, each time completing the video in one shot. On top of that, he had to move his mouth in the "reverse" direction so it looked like he was singing the song when the video was reversed! Based on the outro, he must have learned how to speak backwards, a skill showcased recently on Smarter Every Day. Learning this skill takes months, maybe even years! Sir, I don't know how long it took you to produce this, but this is the most dedicated film making I have ever seen. Astonishing.

[@cc-vm1mw]

I actually had to go through all the nonsense of KZbin registration just to make this comment-however, I thought it was worth it. "The true sign of intelligence is not knowledge, but imagination" (I'm not sure Einstein really said that, but it sounds good.) I find your work...compelling. Like turning the pages of a riveting novel, I am intrigued by what you'll come up with next. This one is going to be hard to beat, LOL. And while I have purchased all your songs (except Eminemium), yes, you have finally motivated me to support you on Patreon; perhaps that is the true test of appreciation. Bravo, Tim. You make life just a little bit more enjoyable. (Loved you mom too!!)

[@voi3077]

My evolution during this song: "Wow, sounds great." "And looks nice, I like the colours." "Wait, that was kinda funny." "Oh my god, it´s backwards, that´s the reason why he was so wet at the beginning!" "One moment, does this mean, he had to sing it backwards too?" I watch the making-of. "He really sang it backwards. WHAT?" (Okay, of cause someone could also only sing it backwards for the recording of the pictures and then sing it normal for the recording of the vocals but I suppose that wasn't the case.) I watch the video again. "Still sounds grat. Woah, there are some really low tunes." (Is "low" the right word? I'm no native speaker but you don't say deep for this, do you? "Low" sounds weird, too. Well, you know what I mean, I hope.) "How can it sound so great and clear in language if it was sung backwards???" "I wanna give more than one like..."

[@voi3077]

Update: I watched the original. "Uh, no. Tim sings better."

[@harmony6643]

Yes, you can call it a low note. ;) I also found this video absolutely great! By the way, what is your native language (if i might ask)? I'm just asking this out of interest since I speak several languages and are really interested in languages.

[@calebgerhard7313]

I figure he lip synced backwards

[@calebgerhard7313]

@Michael Darrow NVM I watched the bts

[@myleskornfeld8582]

I just have to say this video is absolutely amazing. Once I watched the video, I could not believe what I was seeing -- I thought you did some sneaky cgi where you cut the top half of your body, which was going forward, with the bottom half, which was going backwards. Once I saw the behind the scenes video, and understood how much time went into singing this video backwards,was I truly amazed by the effort put into making such an amazing video. I apologize for not knowing your name, but I am truly impressed with this amazing video that you made. The thought of learning the song backwards just blows my mind, and I cannot believe that you made this video. I have already watched this video several times, and it is one of my favorite videos that you have made. You have done such an amazing job with this video. I knew I would enjoy subscribing to your channel, but this video just blows that notion out of proportion. Kudos! Such a truly, but unfortunately underrated, amazing video.

[@acapellascience]

+Myles Kornfeld Tim. Hi, nice to meet you :) Also thanks :D

[@myleskornfeld8582]

+acapellascience hi Tim. Nice to meet you too. And no thanks necessary -- you deserve it.

[@spitfeueranna]

He wouldnt have to sing it backwards, the monotonous beat and timing is the same played backwards and forwards. All he has to do is lipsync it forwards, reverse the video, and match up one way-o-way with another, and all other mouth openings will match. Shrug.

[@myleskornfeld8582]

[@anandsuralkar2947]

[@BassTromBen]

It’s incredibly rare for words to fail me, but you’ve succeeded. This is remarkable in so many ways. As a fellow musician, I can certainly appreciate the execution, but then I realize that you’ve memorized and mimed it in reverse... The science is on point, the video editing is great, it’s musically solid, and the best part... really fun!! I award you infinity points, and thank you for adding your light to an all too often often dull, anti-intellectual world. You’re amazing!!

[@ArcRiley]

The making-of video is great, but it'd be awesome to hear the song reversed as you sung it from the video. The few clips you included in the making-of were mighty impressive!

[@XiaosChannel]

i think the song here is dubbed in later.

[@d4b]

+Xiao'sChannel I think he recorded the audio forward and (separately) the video "backward", singing backward so that he'd get the mouth movements to show correctly, and then simply tossed the audio from the video-recording session. (I agree with +Arc Riley that it'd be great to watch/hear that.) Then he spliced together the forward audio and backward video.

[@XiaosChannel]

+d4b that is exactly what i meant.

[@coloraturaElise]

Ok, awesome on so many levels! Level one.....great singing/harmony--nice full sound, good blend. Level two....that you chose one of the greatest Billy Joel songs. Level three.....the cool video effects with running everything backwards. Level four....the greatest miracle of all......you actually sang the words backwards in real time so it would look like you were singing in forward time when you ran the video back! (I didn't notice at first; about halfway through, I wondered how you were singing forward and going backward, and then I caught a word that was off. Then I noticed the finger snapping looked off.) I wish I had had this video about 4-5 weeks ago when we covered entropy in my chemistry classes....

Initially, the Bohemian Rhapsody parody was the only other one you had done.

I could only wish someone like you was around when I was young. I would have fallen head over heels. Lol! You are adorable, and smart and so talented. And you are even more handsome than when you first started doing this. You make me smile from ear to ear. I LOVE YOUR CREATIVE MIND.

Don't know how many times I've watched this, occasionally it just pops into my head and I watch it again. It absolutely entertains be it the first time, or the hundredth :)

That was effing BRILLIANT! Brain-boggling BRILLIANT! Thank you for doing something so totally outside of normal reality. I think I'm building new synapses right now -- my brain is tingling!

GENIUS!! As a musician I can appreciate the work it took to learn the lyrics backwards and arrange the song; as a video editor I can appreciate the creativity, the planning & execution; and as a visual learner I can simply appreciate the very creative method of explaining the concept. I rarely subscribe to YT channels, but you've got me hooked!

LOL My mom:"Matt, go. Clean. Up. Ur. Room. Now! And never let it be messy again" Me:"Nope. Blame Entropy for making my room so messy, and I cannot know for sure that my room will not be messy ever again, because of the uncertainty principle. SCIENCE SAVED ME" mum:"I shoulda known and never let you learn science"

This video deserves so much more attention than it gets. I'm honestly so surprised it hasn't broken 1 million yet every time I revisit it. Excellent work!

Just you wait.

Holly Molly! This probably took -4 years to make

What's funny is that both I AND my cat Lou loves this song. He comes running to listen whenever I put it on.
