I like the presenter. His pronounciation is very clear and he's easy to understand for non-native speakers and he's the right combination between serious and joking for my personal taste. ^_^
"It's a mere 2 miles away. Sleep tight!"
Elliot, you are awesome.
Some tornadoes hit OKC in May as well. And thanks for talking about overpasses. The 1999 tornado in OKC is one case that has caused meteorologists to discourage this practice. Several people died, in one case a car was thrown into the people.
Has there ever been Misconceptions about Misconceptions? (my lame attempt at being a smart-ass) ;)
Naj Adamu Well, does it count to have people believe in a misconception? Or that a misconception is highly believed in the first place?
Misinception
VBoySLick that's not what inception is
DuneQuakes That might even make it better.
Naj Adamu It wouldn't be a misconception if there were misconceptions about it ;)
Misconceptions about earthquakes might be cool
The overpass during a tornado fact is the reason why I almost stormed out of Man of Steel - that one scene is likely going to cause so many deaths because people are going to believe that's what they should do. If the tornado was close enough to kill Papa Kent (spoilers), it likely also killed everyone under that overpass as debris shot straight thru it like a cannon (yes SOMEHOW THE DOG WILL STILL LIVE).
This bothered me so much, but what's worse was after it was pointed out to the film makers they just responded along the lines of "we're not really concerned with what would have actually happened". Yeah all those people would have died as all that debris would have been flung right under that overpass.
***** it wasn't a public service announcement film. It was a hollywood film depicting an alternate reality. And in reality people would flock to a place like that because of wide spread misconceptions........hence that being the number one misconception in the video....
***** People who take the events of a fictional story as fact might actually be a reasonable portion of the herd to thin.
Also, if the scene you describe took place in say, the early 80s, it was widely spread in that time period, by storm and weather personnel here both in the media and with Skywarn/etc, that overpasses were acceptable shelters if you got up inside the girder areas deep in the upper corners -- so a film portraying people from the 1980s doing, who did such things. would be historically accurate in following the advice of the experts from that time.
***** There are many reasons to storm out of Man of Steel. Laughing at such reasons with friends as they unfold is a much better experience.
***** I have seen video of actual trained weathermen and storm chasers hiding up under overpasses in the 80s and early 90s. It was widely thought back then that if you got up between the girders you'd be relatively safe. Overpass bridges for the most part aren't designed like that anymore and as such it is less safe (granted it wasnt much safer before) these days.
The movie was depicting what lay people/people with old information would have, and most certainly have done in the past. The film was not meant to be a PSA so you need to get the stick out of your ass.
Misconceptions about the Senses. This would include only being 5, the taste map, smell altering taste, and blind meaning you see black.
Cheers Elliot. Always enlightning us. 10/10
I'm no meterogician, but an electrical arc happens when electrons move through (and subsequently ionize) the surrounding air toward a less-negative surface. Power line to hawk, outlet to screwdriver, cloud to ground. Electrons/photons are what are doing the traveling, not the less-electrically charged surface of the ground. So the air might be ionizing in an upward motion, but the strike itself has to physically be downward.
Odd, I was always told that a car is one of the most dangerous places to be during a tornado.
I really enjoyed this. I always thought it was a second a mile. Good to know. :)
I like the way you keep the information rolling. People can process words quickly, slow talkers cause me anxiety 😊
Thanks Elliot, don't usually comment but I enjoy your videos very much!
I would also like to add to Misconception 8. A tornado went through the city of Springfield, MA in 2011 and in 2014, a tornado went through the city of Revere, MA, which is the first recorded tornado in Suffolk County.
Ha, the little "Sleep tight" with a thumbs-up made me laugh. Nice one, Elliot.
Misconceptions about computers/IT! As an IT worker, I run into things like this a bunch!
“The lighting is a mere two miles away from you, sleep tight!!”
Why did I decide to watch this while it's storming? Thanks for the "sleep tight," Elliott. 😕
As always, great facts, but more importantly--Elliott, where did you get your shirt!?
"Sleep tight" best line from this episde
Misconceptions about Men and Misconceptions about Women would be fun. It gets tiring hearing the terms "shark week" when there's barely any blood during menstruation. Also, I enjoy freaking out men when I tell them that men are able to lactate under extreme stress.
I'm glad that I live in Missouri, so know about these things.
If you are in a car during a tornado: START THE DAMN CAR AND DRIVE THE FUCK AWAY
Great lightning photo of Denver!
For the last one about overpasses, trying to stop under the overpass also creates a problem for everyone else on the road as you, and everyone else trying to do this, stop traffic and can create an even bigger problem when cars start crashing into each other.
3:00 thanks for that! I hate storms and always relied on the seconds/kilometre rule so yeah Im more terrified now and will not be sleeping
Misconceptions about Fire
Misconception number one. Fire is hot.
Shannon B Lol. Let's see, "While this is technically true, most people only assume fire is hot because the nerve endings in the skin that detect heat are triggered. This is only half the story, though, because if you compare fires that are commonly or readily created by the average population, they are quite cold compared to, say, the heat from fusion in the core of a star."
***** I read that in Elliot's voice. :P
+Raidfreak there is no fire in the core of a star.
Munashiimaru Okay, "the heat from", carelessly overlooked the fact that fusion isn't an oxidation reaction.
Man, Elliott just breezed through that intro. Hahaha I'll see myself out.
As a resident of Oklahoma, the idea that tornadoes don't hit cities was a surprise. Moore (south Oklahoma City) gets hit by a tornado almost every year.
There should be one done on Amusement Park and attractions in general..some say roller coasters are the most dangerous thing to be on but in fact they are more safer than other rides.
YO WHERE DID YOU GET YOUR SHIRT I FREAKING LOVE IT
Elliot, your eyebrows are perfection
Sweet lightning pic taken in Denver!
"Sleep tight." I got a kick out of that. It was definitely worth the thumbs up I was already going to give this by itself.
Misconceptions about the Higgs Boson
please answer this one for me, does the every day plastics we all use leach BHA into whats made contact with it? and are the study's saying BHA mimics estrogen in the body credible?
The saying "It's too cold for snow" originated in the UK, where it *does* make sense. The UK's climate is quite temperate, and it rarely goes more than a few degrees below freezing. In particular, when the sky is cloudy, that acts as an insulator preventing the ground and lower atmosphere from cooling further (and, being an island, there's nowhere else for colder air to blow in from). The only time it gets *really* cold in the UK is over a clear night (and by *really* cold I still only mean about ten degrees below freezing...!), and in a clear night, there are no clouds, so it can't snow. So, on a really cold crisp night in the UK, it would make perfect sense to say "It's too cold for snow" -- it won't snow again until it warms up a little bit and clouds form or blow in. The saying is linked specifically to the weather in the UK, though, and doesn't apply anywhere else (well, unless there are other places with the same combination of latitude, island, sea currents, as the UK...).
Misconceptions about leaving SourceFed! Please come back!
You wall looks cool!
Yay Denver during misconception 2!
misconceptions about video games
That last one - seems kinda obvious on that point (you're still kinda in the open, but now with a wind funnel of sorts), but what I've always heard was under a bridge at the top near the road (pretty much where the ground meets back up with the road)... How does that compare?
Overpasses being the most dangerous during a tornado actually makes sense. Low pressure and high pressure would be created as a result of the overpass. That is a situation you do not want to be in.
as a suggestion topic, I would love to see corsets, because there are a lot of misconceptions about them.
"Lightning can't strike twice" yes, they can and they will
The lightning trick is "divide by 3" to get it in kilometres. Sound travels 340 m/s, so a three-second delay means just over a kilometre (1020 metres to be precise).
For miles, dividing by 5 isn't that accurate. 4.7 would be most accurate, but it's a bit hard to pull off in your head.
Margin of error using 3 to get kilometres = 3 - 1000/340 = 0.0588 s
Margin of error using 5 to get miles = 5 - 1600/340 = 0.2941 s
So, roughly a 6% error if working in kilometres vs a 29% one for working in miles.
If you want to be accurate in your storm guessing, it might be best to calculate in kilometres then convert to miles if any imperial folk want to know.
To explain the formulas, the top-of-the-head figure minus the actual time it would take for sound to travel that distance gives the margin of error. We know distance and speed. Speed is distance divided by time. Distance divided by speed equals time.
Good video!
1:28 What is the correct on? Fahrenheit or Celsius?
Shout out to the Healthcare Triage Mug balancing precariously on the edge of the mantle.
Do an episode on forensic science
The one about counting the number of seconds to determine the distance to a storm isn't a misconception, it's just people being taught wrong. I've always known it was five seconds a mile.
years ago I don't remember where I was but there was a tornado near by and being near literally nothing we had nowhere to go no ditch
so while listening to emergency radio of where the tornado was we somehow managed to get away at least like 15/20 miles down the highway to find shelter
(also while living in the same place my mom was in the hospital after having hip surgery and tornado warnings went off, she was very willful in getting to a phone to check on the rest of the family instead of getting away from windows)
and that time my school let buses take kids home with tornados warnings everywhere and I got home just in time to hide in a bathtube
wow I'm starting to think tornadoes aren't fans of me
I have seen lightning coming up from the ground once before. I was standing on my front porch watching a storm and lightning happened to strike my neighbors fence right in the center of my field of vision. For an instant I saw a thin branch of lightning from the ground to the end of my field of vision, then the next instant it was as thick as a tree trunk and I jumped back, almost going through my screen door.
Living in Oklahoma, I face palmed hard when the misconception about cars and tornadoes came up.
The last misconception is easily debunkable if you just ask the structural engineer what was the designed wind load. I don't think the meteorologist necessarily knows about the structural integrity unless they ask the engineer...
is the overpass dangerous though?
A tornado also hit Brooklyn in 2007
Random, but I really like your shirt Elliott.
#9 is not a misconception. Literally nobody who was raised in a tornado prone area thinks that. From the time I can first remember, I remember being told that you should never hide in a car from a tornado, and I've also always been told to never try and outrun one in a car.
I knew misconception number eight was not true because I remember a tornado hitting downtown Salt Lake City--a mountainous city--in 1999. One of my high school teachers was living there at the time and his house got totally trashed.
I like your shirt :)
Misconceptions about cholesterol!!! Many people think cholesterol is bad, but actually important.
Of course everything taken too much is bad...
This was more like misconceptions about what to do in bad weather
Misconception: The T in Tsunami is not silent, according to George Tekai.
In English the T is silent in Japanese it is not
It's originally a japanese word, the "tsu" does have a percussive beginning basically like a t sound.
I think when we borrow a word like that, we should try to pronounce it the way it originally is.
-Ronnie Actually the "tsu" is pronounced in both languages. Both dictionary.com and Merriam Webster have the pronunciation listed as "tsoo-nah-mee". It's just that most people mishear it when it's said correctly and that English language contains so many words that begin with silent letters (such as knife, gnome, or know) that it's second nature to assume that the same applies to the t.
If the visible part of lightning is from the ground up then why can you see branches that don't reach the ground or lightning that is only cloud to cloud?
The misconception about weather that bothers me the most is when people mention the likelyness/ percent chance of rain. For example, if it says 70% it means it will rain for sure just on only 70% of that given area's surface versus the total probability of it raining.
Why do we get dizzy when we spin?
I'd like to see a Misconceptions video about glasses or a big question about do glasses make your eye sight worse
Is it true that tornadoes pick up heavier objects (like vehicles and buildings) more easily than lighter objects (like people or lawn furniture)?
Wouldnt that "getting out of your car amd inna low ditch" thing increase the likelihood of being hitnby flyimg debris?
The tornado in Atlanta happened in 2008. I would know that because I was there.
Nice 1992 shirt. We're doing retro 90's stuff already?
Misconceptions about hair. Does gel kill hair follicles, are you only supposed to condition a part of your hair? Hair length speed up with biotin?
Misconceptions about credit reporting
Misconceptions about the UK/France/China/Japan
You need to do one about depression. No one seems to understand it and always have false views on it.
An old Misconception episode said that the human body sheds its skin every 7 months... or 7 years. I cannot remember but my question is if the skin sheds, why do I still have scars when I was a kid. Why didn't those scars go away?
Scars are in the lower layers of skin like tattoos. We shed the outer layer of skin.
Kamel, K It's true. In fact your body replaces every cell in your body over ten years. The reason you still have the scar is because your body replaces most of the cells, as is.
Kamel, K Actually it's even faster than that. Your epidermis replaces itself at a rate of about once a month :)
Please do a misconceptions video about snakes. Venom vs poison, pointed head, and vertical pupil =venomous misconception, slimy misconception, there's a lot to work with.
in sweden, we say that being in a car during thunder is the safest place, cuz they say thunder wont hit it cuz it's metal
I remember when I was in 3rd grade, my teacher said tornadoes never form while it's raining.
Do misconceptions about the paranormal!
Walinkg in cold floor while barefoot, can cause illness?
Misconceptions about Mental Floss! ;P
Movie making and/or acting?
Why does a sunrise/set go from red to orange to yellow to blue, skipping green?
I guess the one at 2:41 is just "wrong" if you don't use the metric system, because i was always told to just count the seconds between the flash and the sound and multiply the seconds with 300m/s and thats the distance (roughly)
*EDIT
I want to see a video of the misconceptions of ballet..... Its probably a stupid one, but I would like to hear what misconceptions are out there.
Could you please use the metric system as well? It's frustrating for the rest of the world watching this to calculate everything while watching.. Thank you! :)
Misconceptions about Mathematics. That would be fun. Im a university math major. :)
I don't mind Elliot, he's a good host. So was John Green
Picture of Denver Co on the misconception of lightning 🌩
What makes it dangerous to stand under overpasses? I'm curious.
Pedro Willadino Ok I found this, it has some more details about tornado protection: en.wikipedia.org/wiki/Tornado_myths
The last one oughta make sense, hiding beneath something that crumble down upon You seems like the worst idea.
I would have liked to see something about "earthquake weather". In California, any time it was unusually warm and still, I'd hear people talking about how it was "earthquake weather" and an earthquake was likely about to happen. Which is, of course, not true; weather and earthquakes really don't have much to do with each other.
I have outrun a tornado, talk about adrenaline overflow, u never know if they are going to change direction
Why do mosquito bites flare up ?
"Freezing rain is the raindrops are frozen." Are there people who actually believe this? Because that's what HAIL is.
Misconceptions About Computer Safety.
Number 9 -- How about driving your car into a ditch?
With your seat belts secured, of course.
Meteorologist here. I'm surprised all of these are correct, since most videos about meteorology like this are at least partly wrong. There are some very minor additions I felt needed to be added;
Snow misconception -
it really can't be 40°C and snowing outside. The temperature at the base of the cloud (or near it) needs to be negative and the ambient air can't be too warm because the snowflakes would melt on the way down and would just fall as rain. Really, it's hard to say how warm it can be; it all depends on the height of the base of the cloud and temperatures all around.
Tornadoes in cities - while the premise is true, it's not just that. While the strongest tornadoes could survive in cities, the weaker ones can't, due to the air being disrupted by buildings. Imagine if you were Godzilla and were running from point A to point B, but a city was in the way. You won't be running as fast when you need to avoid obstacles such as tall buildings. An open field is the best area for a tornado.
