Explain of week:9-Where Do Deleted files Go?


We all delete files on our computers and mobile devices every day, but where do those deleted files actually go? Are they still there in some form? Can they actually be recovered? Is the recovery process difficult? Vsauce discusses the topic in this excellent ‘explainer’ video.

Explain Of the week 8:What Is The Greatest Honer?

  
If you were to ask someone whether winning an Academy Award or a Golden Globe is more of an honor, an overwhelming majority of people would tell you the Academy Award is better. If you were to ask them whether winning that Academy Award is a greater honor than winning a Super Bowl ring, however, you would likely get some confusion and ultimately, an answer based more on the person’s individual preference as opposed to a logical analysis. 

That’s why figuring out what the greatest honor a human being can possibly achieve is an impossible task. Luckily for YouTube viewers, however, Michael from V Sauce has never been unwilling to try and answer something damn near unanswerable. This week, his newest video asks what that aforementioned premiere honor is, and much to Tracy Jordan’s delight, Micahel does touch on the famed EGOT.

Explain Of the week 7:What Color is Mirror?

Explain of the Week 6:What If Everyone JUMPED At Once?

   At the start of the scenario, the entire Earth’s population has been magically transported together into one place.
This crowd takes up an area the size of Rhode Island. But there’s no reason to use the vague phrase “an area the size of Rhode Island”. This is our scenario; we can be specific. They’re actually in Rhode Island.
At the stroke of noon, everyone jumps.
As discussed elsewhere, it doesn’t really affect the planet. Earth outweighs us by a factor of over ten trillion. On average, we humans can vertically jump maybe half a meter on a good day. Even if the Earth were rigid and responded instantly, it would be pushed down by less than an atom’s width.
Next, everyone falls back to the ground.
Technically, this delivers a lot of energy into the Earth, but it’s spread out over a large enough area that it doesn’t do much more than leave footprints in a lot of gardens. A slight pulse of pressure spreads through the North American continental crust and dissipates with little effect. The sound of all those feet hitting the ground creates a loud, drawn-out roar which lasts many seconds.
Eventually, the air grows quiet.
Seconds pass. Everyone looks around.
There are a lot of uncomfortable glances. Someone coughs.
A cell phone comes out of a pocket. Within seconds, the rest of the world’s five billion phones follow. All of them—even those compatible with the region’s towers—are displaying some version of “NO SIGNAL”. The cell networks have all collapsed under the unprecedented load.
Outside Rhode Island, abandoned machinery begins grinding to a halt.
The T. F. Green airport in Warwick, Rhode Island handles a few thousand passengers a day. Assuming they got things organized (including sending out scouting missions to retrieve fuel), they could run at 500% capacity for years without making a dent in the crowd.
The addition of all the nearby airports doesn’t change the equation much. Nor does the region’s light rail system. Crowds climb on board container ships in the deepwater port of Providence, but stocking sufficient food and water for a long sea voyage proves a challenge.
Rhode Island’s half-million cars are commandeered. Moments later, I-95, I-195, and I-295 become the sites of the largest traffic jam in the history of the planet. Most of the cars are engulfed by the crowds, but a lucky few get out and begin wandering the abandoned road network.
Some make it past New York or Boston before running out of fuel. Since the electricity is probably not on at this point, rather than find a working gas pump, it’s easier to just abandon the car and steal the new one. Who can stop you? All the cops are in Rhode Island.
The edge of the crowd spreads outward into southern Massachusetts and Connecticut. Any two people who meet are unlikely to have a language in common, and almost nobody knows the area. The state becomes a patchwork chaos of coalescing and collapsing social hierarchies. Violence is common. Everybody is hungry and thirsty. Grocery stores are emptied. Fresh water is hard to come by and there’s no efficient system for distributing it.
Within weeks, Rhode Island is a graveyard of billions.
The survivors spread out across the face of the world and struggle to build a new civilization atop the pristine ruins of the old. Our species staggers on, but our population has been greatly reduced. Earth’s orbit is completely unaffected—it spins along exactly as it did before our species-wide jump.
But at least now we know.

Explain of the Week 5: Why Do We Feel Nostalgia?

 The term nostalgia describes a sentimentality for the past, typically for a period or place with happy personal associations.The word is a learned formation of a Greek compound, consisting of νόστος (nóstos), meaning "homecoming", a Homeric word, and ἄλγος (álgos), meaning "pain, ache", and was coined by a 17th-century medical student to describe the anxieties displayed by Swiss mercenaries fighting away from home. Described as a medical condition—a form of melancholy—in the Early Modern period, it became an important trope in Romanticism

Explain of the Week 4:How Much Money is There on Earth?

  
  Simply, the answer dependson how you define "money". For the narrowest definition, or what's called "M0", that includes only physical money, paper bills and metal coins that constitute currency. That figure is around 5 trillion dollars. The next step up is M1, which includes all the physical money, plus quickly accessed money like that in checking accounts, and comes in at $25 trillion. M2 includes M0 and M1, but also pulls in stuff like savings accounts and CDs under $100,000. That figure is around $60 trillion. And the last figure, the $75 trillion M3, is much more abstract and not often cited in official figures. It includes institutional money market funds, long term deposits, and other stuff rich people possess that can somehow be spent but confuses the rest of us.
    But, well, that's just currency. And one country's currencies can be wiped out by war or other influences. Or inflation or deflation could change the value of the money you do have. Or a whole host of other things Vsauce covers in the video. So check out the rest of the video, or just sit tight and figure out what miniscule percentage of the world's wealth you've got in your pocket

Explain of the Week 1:Why We Kiss?

  
 
  Why do you kiss? Because it makes you feel good down there? Because it'll hopefully lead to something that'll make you feel great down there? Probably. But what about the science behind why we kiss?
   The scientific effect of kissing has been revealed to burn 2-3 calories per minute and reduce bad cholesterol and stress. But it's not like we knew that when we first swapped saliva! What we did know was that to feed babies more than just breast milk, mothers had to chew up the food to process it for their wee ones. Mouthfeeding. Watch the entire video to explore every nook about kissing.
