Can a space suit be used as a deep sea diving suit that could take humans to the ocean floor? Why?

– Xochielt Sanchez

Answer by Robert Frost:

No.  While the EMU suit is watertight, and we do use it in a 40 ft (12 m) deep pool to train the astronauts, it is designed to hold pressure in, not to keep it out.

At the ocean floor, a diver is under great pressure from the crushing weight of the water above.  A metal box can be crushed.  The structure of the suit would not protect the person wearing it.

What will Apple do about the iPhone 6 Plus bending easily?

– Xochielt Sanchez

Answer by Glyn Williams:

Apple did nothing about phones breaking when put into microwave ovens, being sliced to crumbs by industrial blenders or being run-over by trucks.

Devices break when physically abused and always have.  It's not Apple's problem.

The tests from SquareTrade put the 6 as the most durable device in the category.

What do mainland Chinese people think about the Occupy Central protests in HK?

– Xochielt Sanchez

Answer by Andy Lee Chaisiri:

"With Instagram blocked, how else am I suppose to find pictures of cute photo-filtered girls!?"

Bye bye Siddsel Rasmussen, you will be missed

Instagram being blocked is the most tangible effect the protests have had on mainland Chinese citizens, and it hurts.

On a more serious note, my mainland friends who are at the age where they want to marry and have kids say that their lives are much better than their parents were and they feel that their children's futures will have even more opportunity than they have. To them democracy is merely a means to an end but in mainland China those ends (economic prosperity and general improvement in life quality) are already being satisfied without it.

Mainland Chinese are seeing people from their generations rise up from the same background as themselves and become millionaires and billionaires

Seeing others like them make it gives them hope that they too can be 'the 'next Jack Ma'. In Hong Kong though all the mega-wealthy are also mega-old while fresh highly educated college grads are going unemployed and the start up scene is stagnant, that's the opposite of inspiring hope for the future.

Now if one day mainlanders felt that opportunity was being taken from them and that their children would have a worse life in the future, then you'd see more support for dramatic government reform like the rising generation of Hong Kong is doing now.

Why don’t mothers use masks to reduce crying baby noise in public?

– Xochielt Sanchez

Answer by Maura Rudd:

Because it would be cruel and would likely cause harm to the baby.
As much as I do not enjoy crying babies, that is one of the few things they know how to do. Many years ago I was the crying baby annoying people in public. And they had to put up with me. Now it's my turn to deal with it. And someday in the future that baby will be the adult rolling their eyes when a baby near them is crying.
Kind of the circle of life.

Why was Pluto removed from the planet category and then reinstated?

– Xochielt Sanchez

Answer by Robert Frost:

Pluto has not been reinstated as a planet. I recommend utilizing more responsible news sources.

The International Astronomical Union (IAU) published their official definition of what constitutes a planet in this memo: https://www.iau.org/static/resol… in 2006.  In short, it said that:

1) a planet directly orbits the Sun.  That excludes moons because although they indirectly orbit the Sun, they directly orbit a planet.

2) a planet is massive enough that gravity overcomes rigid body forces and results in a round, almost spherical shape.  That excludes the asteroids.

And

3) a planet has used its mass to sweep up the trash in its neighborhood.  This is where tiny Pluto becomes excluded.

Technical terms lose their effectiveness when they are not precisely defined.  For a long time, the word planet was loosely defined.  The IAU felt it needed to be tightened, so they did so.  The result was Pluto didn't meet the criteria.  That was not their objective, but it was a result.

Obviously, not everyone was happy with the result.  Two weeks ago, at a Harvard panel, Pluto was discussed and the audience was polled.  The audience voted in favor of being a planet.  Various media outlets ran with that and used click bait headlines, but nothing official has changed.  The IAU definition has not changed.  It may, some day, but not yet.

Why was Pluto removed from the planet category and then reinstated?

Is roller skating safe?

Yes – Xochielt Sanchez

Answer by Leonid S. Knyshov:

Very safe

If you keep the correct form, you will not fall backward. That is the biggest fear and it does hurt a lot when that happens. The correct form is as as simple as bending your knees and leaning forward to shift your center of gravity. If you wear a full set of protective gear, you will not get hurt when you fall forward. I have fallen countless times while performing various stunts with zero injuries.

Since this answer got a few upvotes, I might as well teach Quora how to skate. 😉

  1. Wear full set of protective equipment, including helmet, knee pads, elbow guards, and wrist guards that are the right size. Your knee pads should be sufficiently thick to allow you to drop to your knees in the store without discomfort. Inadequate safety equipment will result in injuries.
  2. Tighten the skate boots as much as you can but without cutting off blood circulation. You want absolute stability. Finding correctly fitting skates can be a challenge.
  3. Stand up and bend both of your knees to about 120 degrees. Lean forward so your head is in front of your knees. It will not be possible for you to fall on your back if you maintain this form because your center of gravity will be in the front. Falling forward in full protective gear does not hurt at all.
  4. While keeping one foot stationary, start pushing with the other foot. Initially, just push slowly and just a little to the side and back, perhaps half a boot.
  5. Complete a few laps like that and switch feet.
  6. While rolling as slow speed, start learning to slow down by applying more pressure to your outside foot and turning it toward the other foot. Do not use the heel brake.
  7. Focus more on turning at higher speeds.
  8. As you get comfortable, you will start to skate normally and faster. Turns will allow you to stop with more confidence.
  9. You will learn to brake after your confidence rises sufficiently high to trust yourself to sit down on the heel brake. Experts then take off the brake pads and use wheels to stop faster. The heel brake can potentially interfere when you are skating backwards.

It helps if you have a soccer ball in front of you because it takes your mind off the action of skating and makes you concentrate on how to hit the ball. I previously played Rollersoccer and we had many absolute beginners become able to join the game within a few hours.

If I was teaching you in-person, you would probably be skating backwards within 3 hours.

Is it safe to be an Uber driver?

– Xochielt Sanchez

Answer by Kyle Sim:

If by safe you mean; "Will I potentially contract an STD from a customer who asked me to go to their apartment for some post-party fun?"

Then yes, you may need some protection in that regard.

But seriously. The chance of you getting robbed for your takings doesn't make sense (customers pay via the app) and people you pick up have their credit card details stored within a database as opposed to randomers off the street corners.

It's probably safer than being a regular cab driver. But again, use protection. 😉
