Why does the east coast of North America have so many barrier islands, while the west coast has almost none?

Looking at a map, the whole east coast from Boston south into Mexico seems to have more miles of shoreline protected by barrier islands than not. On the west, from Washington all the way to South America, seems to be solid shoreline broken up only by the occasional bay. Why is this? Does this pattern occur anywhere else?

What is the difference between the streaks left behind from plane/jet engines that disappear quickly, and the ones that stay there for hours?

Is Antarctica 'straddling' the South Pole by continental drift coincidence, or is the spin of the Earth balancing it's position somehow?

Posted: 02 Feb 2019 07:38 AM PST

From the original Pangea, Antarctica seems the most conspicuously positioned and I would like to hear if there is any scientific reasoning why it is 'parked' over a pole.

Do polar vortexes also happen in the southern hemisphere?

The polar vortex in North America is getting a lot of attention, but does it happen in the southern hemisphere as well? If not, why?

How exactly does HPV cause cancer?

Posted: 01 Feb 2019 07:26 PM PST

I heard it a while ago when i got an HPV vaccine. When i tried to Google it, it just said that it converts surface cells to cancer. I think it has something to do with DNA but then wouldn't all viruses cause cancer?

Does taking notes actually help us understand the content we’re learning (lectures, reading, studying)?

Do the different isotopes of Hydrogen affect its properties?

Posted: 01 Feb 2019 10:06 PM PST

For example: I'm reading up on Hydrogens wikipedia page and there it states that hydrogens auto-ignition temperature is 500C (932F). That is for Hydrogen gas, H2.

Now if we took D2 instead or even T2, would that number change?

Would the issues of metal embrittlement differ with the heavier isotopes? Do the heavier isotopes affect combustion either used as fuel as is or in gasoline?

And another question a bit in the same topic: Can you hydrogenate a fluid the same way you could carbonate it?

How do people determine contraception effectiveness rates?

Posted: 01 Feb 2019 01:55 PM PST

They say that condoms, for example, have an effectiveness rating of 85%. How do they study this to come up with this figure? Do they just have a bunch of couples who don't mind having kids try it 100 times?

Why does tetanus cause a red line to form on your arm?

Posted: 01 Feb 2019 05:50 PM PST

A guy I work with was using a nail gun and shot through his finger, few days later a red line appeared on his forearm and it had to be treated for tetanus. What is going on inside your arm when you get tetanus? Why does it cause this red line?

If two particles, Particle A and Particle B, are entangled, and if Person A, in possession of Particle A, breaks the entanglement, would it be possible for Person B, in possession of Particle B, to learn that the entanglement has been broken by using an interaction-free measurement?

Posted: 01 Feb 2019 09:16 AM PST

I read that the reason quantum entangled particles would not be able to facilitate faster-than-light communication is because any attempt to change the state of the particles would cause them to become disentangled. But if you could learn whether or not the entanglement has been broken, that yes/no could be converted into a binary digit. Or if Person A measured Particle A, collapsing the wave function, and if Person B could measure Particle B without interacting with it, then would it be possible for Person B to learn that Person A measured Particle A, because Particle B is no longer in superposition?

Can a material be both electrically conductive and an isolator?

Posted: 01 Feb 2019 01:46 PM PST

I mean, for example, you flip a switch and make a material an isolator, and than flip it back so current can flow through it. Is that physically possible? Could you make that?

Is the weakening of the arctic jet steam and collapsing of the arctic vortex early signals of a impending ice age?
