YouTube channel ‘The Slow Mo Guys’ has posted a new video showcasing its fastest frame rate content to date: 343,915 fps, to be precise. The duo behind the channel, Dan and Gav, used a Phantom v2511 camera to record glass Pyrex dishes shattering with speeds starting at 28,546 fps. At its fastest frame rate, the camera captured the glass shattering at a rate 13,756 times slower than real time.
At the fastest frame rate, the Phantom camera recorded for a duration of 5.1 seconds and during that time captured 19.5 hours’ worth of video footage.
If you're having trouble sleeping, you can check out the full 19+ hour slow-motion shatter video here.
Don't be sad - these new Pyrex cups are junk compared to those from the 1980's. The old ones were way better designed and manufactured, and they are now priceless because you simply can't get them anymore.
Back when Corning made Pyrex it was a robust glass famous for stability and resistance to temperature shattering. It was a popular material for astronomical telescope mirrors due to the low thermal expansion coefficient. But now it is cheap junk glass with a misleading brand name that exploited and squandered the previous reputation.
landscaper1 - if my old cup broke I'd give you at least $200 for yours, assuming it's genuine. If I ever saw one at a garage sale I'd snatch it up instantly, but so far no luck.
apart from a "made in the USA" label or attempting to blow it up with a blow tourch and water in the back yard, how can you tell if your Pyrex jug is made with soda-lime or borosilicate?
It appears the borosilicate ones carry the name "PYREX" in all caps, while the soda-lime-silicate variety is required to be labeled "pyrex" in lower case only.
Oh, and for the record, an 8 cup (similar to that used in the video) original PYREX is worth between $15 & $25. Not worth the effort to even try to sell it.
My Pyrex jug is label PYREX (all caps) AND "made in the USA" so that blows that theory out of the water ;) I suspect the lower case pyrex is just a design change on the label and nothing to do with the type of glass.
Clearly there is a Pyrex conspiracy, threatening America. I suggest we build a 1000 ship Navy to defend ourselves against lower case pyrex incursion. Additionally, a return to universal conscription, let's build an Army to search all lower case pyrex infesting America, and ground these to dust. In the meantime, we'll need to temporarily suspend all civil liberties. Don't worry these will be lifted either once all lower pyrex are removed from sacred America or 10,000 years from now, which ever comes first.
From the list that Dr Jon has provided, the slow mo guys didn't even use the camera with the fastest frame rate. The Phantom v711 can do 1.4 million fps...THAT'S JUST INSANE!
That's right, according to a poster here. The original Pyrex are now "priceless". Thus, worth more than this cheapo $150,000 camera. If you have the original Pyrex, hire ex-SAS mercs to guard them!
That is not comparable. The Phantom flex are filming a single event. That video takes still photos with extremely short exposures, but not in a single take. Every frame is a new event. It can only stitch events that are highly repeatable into a timelaps movie.
We're all time travelers. However, we can only go in one direction at an approximate speed of 1 second per second (relative to object at rest at earth's sea level) ....that's my smart a$$ comment for the day. I'm done here.
unless your in motion or at an elevated position...then you are traveling at a different rate due to time dilation. Your head is moving slightly slower through time than your toes....or is it the other way around...damn you Einstein!
Yup (how did I get stuck in this conversation?). The faster you go, the slower time goes. You're on a curved surface (big Little Prince). Your head is moving faster (by a tiny bit) than your feet. So, time is slower where your head is. I think.
special relativity: time slows down the closer you get to light speed general relativity: time slows down the closer you are to a massive gravitational source. Your head is going slower through time because its taking a wider circular(ish) route but speeding up through time because it's further from the earths surface. The net result is......a headache at this point ;) As for bats, well they're just crazy so who knows.
General relativity: there is no (unique) time. It is relative, after all. Special relativity: still there is no time. Even if you fix a time function, you head is "moving in time" with the same "speed" but its "proper time" from one moment to another is shorter.
It is like a spiral around a vertical axis between two levels. The spiral arrives at the same vertical level at the same moment as a particle along the axis but it is longer. In relativity, it is actually shorter.
The Panasonic Lumix DC-G100 (G110 in some regions) is a mirrorless camera designed for vlogging. Its 20MP Four Thirds sensor is paired with clever tracking audio technology, but we have our reservations.
The Olympus PEN E-PL10 is the latest in the company's entry-level mirrorless line-up. It's a beginner-friendly camera that does many things well, but ultimately doesn't stand out amongst its competition.
The Nikon Coolpix P950 is a powerful superzoom compact camera, built around a 24-2000mm equivalent zoom lens. Successor to the popular P900, the P950 adds an improved EVF, Raw capture and 4K video. So is it worth $800?
The Fujifilm X-T4 brings image stabilization, faster shooting and a bigger battery to the X-T series. It's not without its shortcomings but we found it to be an excellent stills and video shooter.
With its unusual form factor can the Tourbox aid the editing process? Will its price and variety of tactile controls appeal to photo and video editors who would like to streamline their workflow?
