top Why Are We Made of Matter?
of course matter can pop out of nowhere - it happens all the time, see
Virtual Particle. What is different here is the vast scale at which it happened, and where this phenomon applies to the origin of the Big Bang
Don't throw away a theory because you don't understand how it is started. The Big Bang Theory is simply stunning in it's ability to explain almost everything in the know universe that we observe. It is up to someone else to work out what may have triggered it.
This is just like Evolution which brilliantly explains almost everything we see in terms of life as it is. but evolution is not Abiogensis
When you understand that Evolution and Abogenesis are different things, as are sex and embryology, you will also understand how you mixed up the Big Bang Theory with another area of study which is about multiverses, unverse bubbles, oscillating universes, God's Poke, and other interesting ideas that are today all still in the realm of speculation - because we have no way yet of seeing which of them could be true.
Big Bang cosmologists work on what is observable and testable and predictable.
Big Bang cosmologists are not expecting to find out how to create a big bang, but describe what happens after it occurs.
top USB Reversable Cable Images Emerge
IAAP (I am a physicist).
There is nothing wrong with "5 volt power transfer".
It is just saying that the power (whether 100mA or 100A) is always transferred at 5 volts, and not at 0.5 V or 50V.
What is strange here is the "power transfer rate". Power= "energy transfer rate". "Power change rate" would make sense when talking about power ramp up, (i.e. how many milliseconds it needs to go from 100mA to 1A).
A Type-C cable with100W racing through it sounds like a fire hazard to me.

The difference is that a taxi driver paid 30,000€ or more for his taxi license, and you paid nothing for yours. That's why they have this protectionist racket, because they are protecting their "investments".

top Cisco Plans $1B Investment In Cloud
My company has employees in over 40 countries globally - 100 of us need to daily collaborate to build demo, download and upload virtual machines. A cloud provider gives us that for about 100,000k€/year and gives us servers in US, Europe and Asia. There is no way we could do that internally for 2 or 3 times that price. Cloud is a great solution for us - data loss, hacking, snooping etc are not issues because these are customer facing demo machines, and we download what we want.

top Ask Slashdot: How Do You Manage Your Passwords?
I also use keypass+dropbox+iphone+Minikeepass.
Why is a keyfile an excellent option? If you only have 500,000 files on your computer (I bet you have less on your iphone), it can't take long to try them all - that is less secure than a 6 digit PIN, isn't it?
Or do you mean keyfile+passphrase? But isn't the effort to find the path of the keyfile more clicking/typing than an extra 6 digits??

top Starbucks Phone App Stores Password Unencrypted
Is there a genuinely secure mechanism for an app to store a password internally? I imagine they mostly just store an encrypted version of the password using a standard algorithm with an fixed "unknown" key/salt in the code. Isn't this just an example of security through obscurity?
top New Class of "Hypervelocity Stars" Discovered Escaping the Galaxy
This speed is still very fast if it is taken relative to us or to the galactic center. The galaxy's speed relative to the cluster plays no role at these sizes and time scales.
"sitting idle-ish and the galaxy zipping past" is the classic Relativity - it makes no difference - both are identical. In either case something caused that Star's velocity relative to us to by very different.

top US Coast Guard Ship To Attempt Rescue of 2 Icebreakers In Antarctica
go and look at
Ozone depletion and see that the alarmism was worth it because the world did ban CFCs and the charts show the improvement since. What we need is global coordinated action on the issues of today
Icebreakers being stuck in ice doesn't say much about climate change - incidents of such icebreakers stuck in ice over many decades may say something. Don't confuse an incident with a trend
I am sure there are many stupid Americans in New England seeing how amazingly cold it is this week and mocking Climate Change. (I live in Central Europe and we have at the moment one of the hottest Januaries on record). Climate Change predicts weather extremes because there is more energy available in weather systems to push to hotter and colder extremes.
That thick ice in Antarctica could be an example of climate change if, for example, more ice is rolling off the land faster, or climate change has changed currents to push more ice into that bay. Only objective longterm observations can help here.
There are problems with Alarmism, but it was right with Acid Rain in the 1970s, leaded petrol and Ozone in the 80's - those problems were reversed - and the scientific community is in consensus that CO2 today is a far more serious issue and we need alarmism before we reach tipping points.
I would rather take action with alarmism, then do nothing out of cynicism while species go extinct and Africans and Bangladeshis try to emigrate in their millions.
top Bill Nye To Debate Creationist Museum Founder Ken Ham
Ken Ham has been playing this game since at least the early 80's. He is not an idiot - he is just convinced that Genesis 1 is literally true and that all Genesis-deniers are deceived by the Devil and keeping people from following the one true Creator Jeezuz. This will not be a debate at all - they will both be ignoring each other's positions, digging into the sand and grandstanding - and Ham's organisation gets 25$ per attendee and millions of Youtube views and other media attention.
If Nye does well, then Ham's people will say that Satan is clever or that man's wisdom will be shown foolish at the Last Judgement and warn his followers to not follow the Serpent's smooth words, and that listening to these humanists will imperil your soul.
Ken Ham is an Evangelist with the mission of winning souls by "upholding the authority of the Bible from the very first verse". That is for him the only goal of this "Debate".
