That Glow Fob was LEGIT surprisingly cool! That was probably the strongest glowing gadget I've seen so far - which product from today was your favorite? Afterwards go watch "I Bought... Nothing?! | 10 Ridiculous Amazon Products" ➡ ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gn9uUjwBaEk.html
Eric well i doubt he'll see it. He has wrong i know. But if you really want to know how to do it there's plenty of videos and articles about it. If you don't like it so be it, I have nothing about it. Everyone have different likings and interests.
I'd imagine if a team of scientists were to be able to stop the progress of light and restart it via super-cooling a vacuum and running a light through it (they did, look it up) then light is effected by it's environment. Because of the speed at-which light travels at room temperature there wouldn't be any noticeable difference in it's path. But with a strong enough source of gravity and the natural vacuum and cooling that is space, the effect on the light should be easily visible. This is why if the closest star to us (other than the sun) were to disappear it'd still take 15 years to be seen on earth.
4.364-4.368 light years ( Proxima Centauri atm) is 4.364 years for light to travel the distance in free space unchanged from the original photonic pattern emitted (roughly 81000 years at current maximum velocity in space 56000 kmh so 489,552,000 kilometres away from earth), not just slowed with temperature alone.
The weird thing is that gravity does affect light. Somethings have so much mass, like a huge star, or a black hole, that light starts to curve, and even can slow down. Einstein figured this out, and he theorized that if any solid matter could travel at the speed of light, it would have more mass than the universe, an time would stop completely.
Fun science fact!!! The model that you know of an atom is incorrect and we will never be able to see what an atom actually looks like because an atom isn't technically visible!! it exists within certain points upon a wavelength so no amount of magnification will ever be able to see it.
He also didn't follow the instructions what so ever, I have one, it's one of a new class of bluetooth things that actually need to be right on the phone. It's super low power to keep the noise floor low, it needs to be placed flat on the back of the phone while you're taking a reading. On a side note, when you but it, (at least in the us) they have to have a cardiologist read the initial sample before they can give it to you so it takes up to a full day to use it the first time. This thing is for people with actual heart issues, if you don't have anything going on, or any serious worries, it's not really all that useful. It works as advertised, still a little noisy compared to professional equipment but reasonably viable. if you have worries about any of its readings, you can pay them $20 and they have a cardiologist read the output in a couple of hours.
I laughed when I saw you reviewing that keyboard since my boyfriend actually have had that same keyboard for years now and it works for him but the only draw back is the fact that the keys are a bit bigger so it makes it harder for gaming.
Oh man, the Kardia generates an EKG, the app is just a pulse. The point of the product is for patients with known heart arrhythmias (i.e. a-fib) to monitor their heart if they go into an arrhythmia and to notify their doctor. Medication needs to be adjusted/started since these issues cause heart attacks and strokes.
I came here to post the same. This was my first experience watching this guy's videos. Rule #1: don't review a product if you don't understand what it does. I won't be watching any more of his videos.
No doctor would make changes to a patient's medications or treatment, even one with cardiac care experience, based off of such a simple ECG. There needs to be at least 3 points of contact to accurately measure a lead for electrical conduction of the heart. Which is why a 3 Lead ECG uses a red, black, and white wire system to typically measure leads 1, 2, and 3 with lead 2 being the most commonly used for diagnostic in a non 12 lead system. The black and white wires alone (left and right shoulders respectively) are not enough to measure an accurate heart rhythm for diagnostic purposes. Also it is not called an arrhythmia unless it becomes irregular and out of range for a Normal Sinus Rhythm. So please if you're going to tell someone that don't understand how a product works or the bodily system it monitors not to review it, perhaps you should also become more familiar with the system and body system yourself before you complain to them for not knowing. And please tell me more how you'll never watch another one of his videos based off the fact that he inaccurately reviewed an personal ECG monitor, when half of what he reviews is done without thought, or education, or experience and often without even reading the package instructions. It's not like this is his first time making a messed up review on something because he was a dumbass, yet you've made it this far in his videos without (I assume) having had other issues. Which means you're too stupid to realize he got it wrong all those other times and got lucky this time, or you've not cared before, maybe a bit of both. Please take the high road now though it shows that you're as much of a douche as I am for pointing out you're a dumbass.
Yes, I know all of this. The main use case for this is detecting afib so that a patient has confidence in whether they are in NSR or afib. Most patients have medicine they can take when they go into afib, so this is helpful. Also, there's a good likelihood, according to my research, that afib can be detected with 2 lead as the P wave is often seen on lead II. This was the first video I watched from this guy, and the fact that he was reviewing a product not for its intended use case soured me.
First, I said that it's for them to notify their doctor if they "go into an arrhythmia", which is what it's called. Maybe my use of the word "notify" was confusing, but I did not have any intention for the thought of a doctor just going ahead and giving a medication to someone based off a personal device. I never said anything about this device being superior to an actual 12 lead EKG, to which I also know how it works. Lastly, I wasn't the one who said anything about not watching his videos anymore. You confused me with another commenter.
I have never been so happy that I got addicted to these videos. My family is experiencing a bed bug problem, but with two small kids running around it is fairly hard to distinguish food crumbs from the little bastard's eggs. As soon as I read bed bug on that flashlight, I was all over it. That'll make detection and clean up so much easier to see. Amazing find.
The Gamer the whole time I am screaming at him saying 1 and 0. Thinking to myself I can not be the only programmer here. Sorry Matthias still love your channel.
I got that UV protector. It works for other things like activating glow in the dark paint. Its also useful for my dad to see where me cats... you know.
SuperNaturalWoman Gaming if your cat is peeing outside the liter box you should see a vet. This is not normal and can often be the cause of serious health conditions.
Can see where me cats 😂 your dad wants to see your cat with a u.v light 😂 he actually wants to see if anything is showing up on your cat so he can beat the man up 😂😂
In general relativity, gravity affects anything with energy. While light doesn't have rest-mass, it still has energy --- and is thus affected by gravity.
But, since light is so fast it can circle the earth 7.5 times in a second, we don't often see this affect of gravity until it's on a large scale. Really gives you an idea of how far a light YEAR is.
Yes it does, I forget when it was first observed, but stars can sometimes be seen when they are behind the sun or other things of similar mass and density.
That BattleBots toy was legitimately ONE OF the best products I've ever seen on this channel. I am about to go check if it is still for sale and I'm going to see if you can get more of the BattleBots. I could see me and my buddies sitting around on Friday night drinking some beers playing BattleBots
my god "Black Holes are the absence of matter" smh XD. Light has no mass yet somehow possesses momentum. This means that gravity can affect the path light travels and additionally allows for collisions with light to impart force (hence the idea behind solar sails). Even if light did not possess momentum It still follows any curvature in space, such as the curvature created by mass.
It's funny because black holes are the opposite of the "absence of matter". They are the result of collapsed star core after going super nova. So they are super dense matter creating such strong gravitational pull light cannot escape its pull.
Glow in the dark key chains are useless, it's in your pocket all day so there's no charge and you would have lost your keys for at least a hour in a lighted area for you to find it only when it turns dark.
I got a vile exactly like that one, but it has Tridium(the same stuff they use for night sights on guns and in some glowing watch faces) and it glows whether it's been exposed to light or not. It's been glowing for the past 3 years, it just doesn't glow very bright(but enough to stand out in darkness).
fuzzlenutberry tritium ones are the best, because tritium emmits beta radiation if o remember correctly, and that radiation exites a phosphor film, that emmits photons, so its bright and lights up forever, you dont need to shine a light at those ones
The binary of the clock refers to the on or off position on the led's. If the led is illuminated it is a 1, if it is not illuminated it is a 0. You count the illuminated led's in the 1, 2, 4, and 8 rows to get the time.
Matthias deserves more subscribers. He always has really good content. The videos he uploads are his own, very useful to all types of people. And most of all he doesn’t try to stretch out his videos to the 10 minute mark. This video for instant one video 20 minutes long. Any other RU-vidr would make a Part 1- 10 minutes long, then Part 2- 10 minutes long AND OR put/ use only half the products so they have a video to upload Today and Tomorrow.
Sorry but I had to tell you that opaque means unable to let light pass through it, so you can’t see through it, but some objects like paper can become translucent, able to let some some light through it, sometimes you can see through it but in this case, you can’t see through it and if you’re wondering, transparent, able to let light completely pass through it is different then translucent. BTW I know that this was incorrect grammer.
Karen Dobrowolski oh that's creepy!! I always thought there would be a way to see in.. definitely bringing something to cover peephole at hotels!! Tape, post it note, something!! I always have one over my lap tops Web cam..Just in case!! I've seen to many Crime drama's where bad guys hack into those!!
11:50 Matt:washable keyboard? Oh this is perfect for you Connor beacuse you just spill all of your keyboards... Me:he spills his keyboards?? HOW DOES CONNOR SPILL HIS KEYBOARDS!?!
