Why Ancient Roman Concrete is Better
Roman concrete structures still stand after thousands of years. Meanwhile, modern concrete structures deteriorate and collapse within decades. Why is Roman concrete so durable, and why does modern concrete suck?

North America's WORST Earthquake is Coming
zhlédnutí 238KPřed rokem
North America's worst earthquake is coming. In the Pacific Northwest, tension is building as the Juan de Fuca Plate collides with the North American Plate in the Cascadia subduction zone. When this tension releases, a mega thrust earthquake will occur, destroying much of the region. It is only a matter of time before this dramatic geological event occurs making its understanding critically impo...
Why Headlights are SO Bright Now

Car headlights are bright and dangerous, but why? Maybe you've noticed: In the past 10 years, car headlights have become extremely bright. So bright that it is often very difficult to see the road when driving by an oncoming vehicle. But, headlights haven' always been like this. This is a story between car manufacturers and consumers. Technology has allowed for increased visibility on the roads...

That this bright light issue has gone on this long without it being properly addressed is just crazy/insane.
Aren't there LED headlights that emits just like convensional halogen bulbs to reduce glare? If none, just make it a rgulation to bring back halogen headlights. It really very very difficult and dangerous with this modern headlights.

Anyone living on the coast is going to be F’d.

I would like to know why y'all saying 50 years. Its literally going to happen at anytime any day. The evidence of that is very clear
So am I the only one here that see's a simple solution - CHANGE THE COLOR SPECTRUM FROM BLUE TO SOMETHING ELSE. DUHHHHH
Yellowstone going off is something to worry about more than this, it'll be easier to recover from a large earthquake than Yellowstone which will be worldwide devastation for decades.
Yellowstone hasnt erupted in an extremely long time, “the big one” is something that happened regularly every 300~ years
Not because lumens. Putting led bulb behind the optics of headlights, whether if it’s projector or reflector is called lux. Driving cars with halogen headlights are not bright enough, not safe enough, and u can’t jack shit on the road. With the correct type of led bulbs. Me and my family feel much better and much safer to see better at night with right type of led bulbs like Lasfit, Auxito, and Sylvania led without blind others. As long as it mimics the same beam pattern, fix the correct beam pattern height, fix the orientation of the led bulb facing 3-9 o’clock position, make sure the led two sided chips are the same size as the coil filament. U will be fine.

When you talk about the ghost forest and the land plummeting 2 meters, it also moves west at the same time. So not just up and down but side to side as well. This is important to think of it moving in three dimensions as the crust rebounds because not all of the crust drops but also lifts at the front edge of the subduction. Teaching just the drop part is not giving the students the big picture of what's happening to the crust when the earthquake is happening.
I know the simple answer, its because there aren't enforced regulations preventing the blinding lights from being manufactured and sold
Were the guy that made this video high? "Denmark is wonderfully designed," the narrator says, and meanwhile the video shows a Dutch city, I think - at least it's certainly not a Danish one.
The farralon plate remnants is now thought to be the source of stress build up in the new Madrid seismic zone. Interesting how both areas are waiting for the big one and are possibly caused by the same thing despite the distance.
When California goes Yellowstone goes so we mine the fault lines at the salt n sea for lithium and subsidize electric cars.

"Volga river is the largest river in Russia" - that's literally shocked me: how in the 21st century it's even possible for someone with access to the internet to say such nonsense? Dude, the Volga is only the 5th/6th largest river in Russia! The largest would be the Lena. I mean, you're making a video, not just having a small talk with your friends! Where did you get this information? You just pulled it out of your head? That's not how you make videos, that's a China-level quality. Where did you get your education? College probably did a bad job. I'm sorry, but it is what it is - you need to read something before making a video, you're not talking about science fiction. And your video just consists of such mistakes. For example, you've mentioned Russia's ports that freeze during the winter, but what about ports that don't freeze during the winter months? Of course, it would be great for Russia to have more warm water ports, but Russia already has several of them and you didn't mention them in the video: Murmansk on the Arctic Ocean, Kaliningrad and Baltiysk on the Baltic Sea, Novorossiysk, Tuapse, Sevastopol, Yalta, Feodosiya on the Black Sea, Kerch and Port-Kavkaz between the Black and Azov seas, Nevel'sk, Holmsk and Zarubino on the Sea of Japan, and also - Petropavlovsk-Kamchatskiy located in the second largest natural harbor in the world - Avacha Bay on the Pacific Ocean. All of them don't freeze throughout the year. And since Russia has the biggest in the world fleet of nuclear-powered icebreakers - is freezing of some ports such a big problem? Again, even ports that do freeze in winter months - they don't go on holidays at that time, they still work but with the help of ice-breakers they`re not "useless" for the winter time as you said in the video. Pure joke. Going next: you've talked about problems with agriculture - and again, problems with agriculture today are mostly due to Putin and his corrupt government which doesn't care about people and the country itself. It's not about geography: Russia has one of the most arable land in the world and which is even more important - most of the arable land in Russia consists of the most fertile type of soil in the world called chernozem - it`s even a Russian word (chernozem = black land/ground/earth), because this type of soil was found in Russia and Ukraine and now Russia still has around 55% of all world`s chernozem soils. I can even rely on my personal experience: i live in the central Ural mountains region and almost all of the food in local supermarkets is Russian-produced (it was like that even before sanctions and isolation) with a very good-quality (even with such a bad situation in Russian economy today). My region, for example is famous for its milk products. Of course before sanctions there were many products from all around the world (as you understand they have been replaced by russian analogs now and you need to go to a bigger supermarkets, shopping malls to find these products, but i personally don`t care, i still buy what i`ve always bought before), but still - fruits, vegetables, drinks, milk and bread products, candies, and all the other stuff possible - most of them are Russian produced. In winter such "tropical" stuff as watermelons and melons and others are come from the tropical countries but in summer - we have around 4 sorts of watermelons and melons in a small markets which come from the different Russians regions which produce them (and that`s considering that i live in a small town in the region that doesn`t produce watermelons or melons at all). And even without all of that i have said - your phrase "32% of Russia is too cold for agriculture" still makes no sense: it`s just sounds not logical. I can say "Most of the West of US is too hot for agriculture" - so what? It`s just sounds weird and wrong, 32% of Russia is not all of it and considering the fact how big Russia is - all of other 68% of its land is millions of kilometers. Also a point "Naval power equals power" - is pretty senseless in this world today, it might have been a thing a long times ago, but today - it doesn`t even matter in what country your factories are set up. Somehow Russia was one of the greatest military powers in the human`s history and with a pretty decent fleet, maybe with not that many free access options to the world`s ocean. And if we get back to water resources - seriously, Russia is on the 2th position in the world by total renewable water resources, only Brazil has more of them. Lake Baikal itself has around 20% of the world freshwater resources. The 1th and 2th biggest lake in Europe (without Caspian Sea) - Ladoga and Onega which are located in Russia are not consist of the fake water too, you know. And talking about rivers in Russia - there are 2 rivers in Russia that are bigger than Mississippi: Lena and Yenisei. There`s lots of navigable big rivers both in European and Asian Russia. "The East of Russia is protected only by the cold of Siberia" - is just "lmao" to say the less. You probably never heard of Russia has 8 climate zones and Siberia itself has 4 climate zones (that`s without Far East of Russia which has 4 other climate zones). Also seems like you forgot about seas and oceans - isn`t they one of the best protections against invasion?) And even if we`re talking about land borders - Far East of Russia and Siberia are covered with many different endless mountains and volcanos - does that say something to you? These mountain ranges are even sit on almost all of Russia Pacific coast making invasion even without a cold winter (if it was cold in Far Eastern Russia) impossible. Only West Siberia has almost no mountains (only Ural mountains which separate Europe and Asia) - but, surprise - West Siberia is a one big swamp. We can add to this list of natural protectors one of the biggest forests in the world - Siberian taiga. Siberia and Far East wouldn`t have to worry about the invasion even if they were tropics. And finally, your statement that "Russia is poor because of its geography" makes me laugh. Lots of natural resources such as water, forests, oil, gas, coal, gold, diamonds, etc. - i guess because of that Russia is poor. If you`re trying to say that it is hard to manage - well, i`m sure you didn`t study history of the United States well. It`s about overcoming negative aspects of your country`s geography and maxing out benefits of your country`s geography. US did it and now you can find tons of videos of how "US blessed with its geography and that`s why they are rich" - but nobody now remembers the unsuitable for agriculture Great plains, dry, boiling hot and covered with mountains Wild West and suffering from Hurricanes and diseases Southwest. US could sit and do nothing today saying "what`s the reason to develop southwest if every year Hurricanes and Floods destroying infrastructure there?" or "why we need to build economy in Texas and Arizona - it`s too hot and dry there, all of local resources wouldn`t make us going there and building something there!" - but US just overcome some disadvantages of their land and used their advantages so nowadays people think that in US land there`s not even a single problem with America`s geography. Geography plays it`s role, but to say the country x is poor just because of its geography - is going against what history science and economy teach us. Again, sorry, but those non-scientific conclusions - i just can`t stand them and it doesn`t matter what language do you speak and in what country do you live: if you don`t know something - just don`t pretend that you do! This is the problem of most people on this planet, but which is worse - when people who don`t know something but despite it decide to talk about it.
I live on an Island and for 60 years people have predicted earthquake castrophy , the earthquakes we have had are not the issue its the crazy people trying to scare everyone 😅
What island and where
@@Joe_Monkey_Rogan Beside the Salish sea..........also called Paradise by locals😉
This is very interesting on explaining how this forms two parallel mountain ranges, and why the coast ranges aren't volcanic. I don't remember ever seeing any one address this before.
I love my ice blue 10k led lights I always ride with only my highbeams on
10,000k ice blue led are more for show. If u put them in high beams it gets the job done. Same for fog use. Low beams, I would not use them because it’s not bright enough. Unless it’s a switchback.
Deepside, great discussion or presentation. I think about the only thing you missed is the size of the emitter or reflector. Use to be reflectors were about 4-inches or larger in diameter, until LEDs became the usual headlight.
I’ve almost got in some serious accidents from being absolutely blinded by oncoming traffic, being blinded for a few seconds and not being able to see any other traffic on the road is definitely a serious problem. 5 to 8 seconds of driving completely blind is beyond dangerous.
I live in Indiana, so we don’t have to worry about this.

Pu jet Sound not however you butchered it, and it's 'Grays' Harbor, not Gray Harbor. Getting all the details right is important as the others
😂 Pudgette.
30% my azz! More like 90
Depending on the led bulb and the wattage. So it’s true. Either from 30%-100%+. Depending on the led bulb like I said.
The eye doctor that I go to says that he hears about these overly bright headlights at least a dozen times per day. NTSB needs to put a stop to these blinding lights.
Small chump change compared to New Madrid Zone.
This is categorically false. Also, not sure why it has to be a competition? Too much hometown pride perhaps?
@@Dnttou0497 very true,and nothing wrong with pride. Do you wake up ButtHurt?asking for a friend
I'd say the trend of using darker-tinted windshields is part of the blame. Try to use 40% or 60% ilm and you'll see why people want brighter bulbs.
People need to start suing car manufacturers for this shit. It's out of control.
Why are we suing the car manufacturers?
@@StolenJoker84 Because there are no regulations that dictate how dim lights can be, so manufacturers are simply trying to outdo one another?
Fingers crossed!!
Most of the problem comes from car owners themselves trying to make their car seem "better" by replacing the halogen bulbs with LEDs, which do not work properly with the optics in halogen fixtures. Halogen bulbs have a single filament which is a single bright point, while retrofit LED bulbs typically have an array of LEDs spread out over a large area. The lenses and reflectors in halogen fixtures are not designed for an array of LEDs so they send light in random directions. Some car owners love retrofit LEDs because many cars only offer LED lighting on the "premium" model, so swapping the halogens for LEDs they believe makes people assume their have a premium model. Also, people with older cars that never offered LEDs tend to install them to make their car appear newer than it is.
mate, the difference is one of them is built out of natural rocks... the other reinforced concrete, of course the natural rock will last a while... so the difference really has nothing to do with "concrete"
Well……should we move or just kill ourselves ?
The 7 years God Jehovah warned you about. 2017 NW to SE the eclipse crosses over Carbondale illinois (wouldnt know this town if it wasn't for meeting the two gay brothers who live together, screw each other, and mother in Marion who keeps their SS disable check; gee sounds like Sodom). Now 2024 the path crosses like a great big X from SW to NE marking Carbondale as 90 miles north of the New Madrid late-for-quake which was last predicted for an opposite pull of solar and lunar tug (which is how i discovered the matching mythology to 1918bc July 18 sothic star rising with a 7am quake in the year Shem Melkizedek age 550 went to Abram and predicted it in year 452) giving us the magic-X marks the spot from two eclipses 2017/2024 for earthquakes at 7am and 7pm. Already they claim stores will be empty and gas stations too; now add the high alert for 9.0 earthquake and you have an armageddon the people were lured too. As the bible says about ALL armageddons; Jehovah gathers them together and lures them as he does to Gog and Magog. HE says dont forget to notice the comet there beside the sun, and HE says do look for the asteroid which will hit us in 10 months. I'm making sure i have round-trip gas to a smaller town to see it.
I hate LED headlights so much! Flash your high beams at them at the last minute! Don't put up with this!
Make sure u get the right type of led.
Bla bla bla
Thankful Vancouver Canada allocate huge funding to do seismic upgrade to major infrastructures since 2014. But we still need more to prevent catastrophic events after a magnitude 9 or larger earthquake, such as emergency power and essentials for people to survive until the rescue arrived
Would Eastern Washington feel this?
Bro the manufacturer aren't the asshats refusing to turn off their brights or accept that their lows are killing everyone else's vision.
You sound young. I'm 65. Been driving since a teenager. When I started to drive cars had round headlights with (dual) tungsten filament incandescent bulbs. They were not particularly bright but the lenses were scientifically designed for both efficiency and control. Full beam is up and straight ahead, dipped is down to the side of the road. Halogen bulbs started appearing in the 1970s, not 1959. They were much brighter. That was a plus for high speeds but unfortunately the timing also coincided with the widespread adoption of wedge shaped headlight lenses. At that point I believe designers totally lost control of vehicle lighting. I am very aware of lightbulbs, being a collector of antique scientifically designed (Holophane brand) light reflectors and refractors, and only tungsten bulbs provide a controllable single point light source. All other bulb types fail. They copy the shape of tungsten bulbs but do not do the same job. (A bit like things made in China that look like familiar objects but fail to function like them.) I was taught lighting design at architecture school. In the domestic and office environment we were taught that fluros are okay for background lighting but not for work lights. Fluros always flicker at 50Hz, and not being a single point source create light without shadows. It is maddening, literally. A life without shadows drives you nuts. (We were also taught not to paint a child's room with walls and ceiling same colour: creates the same effect as whiteout in the snow.) While at university I spent one summer working with the university electricians changing bulbs and tubes, a lecture theatre at a time. I became very familiar with them. Taking a break from architecture school I worked for a few years as a gibstopper (drywall plasterer) just as halogens were being introduced for domestic use. What a lot of nonsense that was. The same time as downlights became popular. A million nasty bulbs throwing light at the floor and leaving the ceiling dark: how nuts is that! The global warming nonsense has put paid to tungsten bulbs and so I have been forced to try out other light sources. In a fully enclosed reflector-refractor compact fluros are adequate and less likely to burn out wiring. LEDs are absolutely hopeless. It is very hard to get a reflector to control them. I have read about the widespread installation of 5G cellular networks and how these have been sold by having streetlighting included in the package, LED of course. What I read is that the LED lighting is driving the wildlife crazy. I assume the same goes for humans too. No other artificial light source is better match to the human eye and brain combination the the single point light source tungsten filament incandescent bulb. So, your timing was a bit out on the halogens so you probably were not around to see the start of the failure of car lighting. Later types of lighting just got worse. On top of the lighting technology other technologies contribute to bright light effects. The change in car shape to avoid pedestrian harm, followed by the popularity of SUVs raised the height of headlights, making it harder to control intrusion of light into the cabins of other cars. And improved breaking means that drivers are inclined to follow closer again leading to light intrusion. I do not see any improvement in the near future.
This year will be bad with disaster's for China but next year will be a very very bad year for California earthquake will have effects on yellow stone volcano but our Lord has said that the earth will go through growing pains
I've literally experienced road rage because they guy with the bright lights was offended that I used my hand to shield my eyes from the side mirror reflection. These people are unhinged
For real. Had a dude turn a supernova on me because I dared to flash my brights at him to say "hey you mind turning off your lights since we're both waiting on food at a fuckin sonic..... no oh so .... nope you definitely misunderstood and definitely got ass mad. Fuckin red necks.
