### It's about time! NASA's orbital atomic clock a boon for deep space navigation – if they can get it working for long enough

#### Re: "Light signals can sometimes take up to 20 minutes to journey from Earth to Mars "

Perhaps it's referring to when Earth and Mars are at their furthest apart along their orbits vs their nearest. (or points in between)

### Man found dead inside model dinosaur after climbing in to retrieve phone

Where was the hole that he climbed in? and Why was there a hole big enough to fit a person through there?

### Brit brainiacs say they've cracked non-volatile RAM that uses 100 times less power

#### Re: "Within the next decade we'll either have it or we won't"

One other possibility is that we'll kinda have it.

### Literally rings our bell: Scottish eggheads snap quantum entanglement for the first time

#### Re: It takes time for A to affect B, even if you can't measure it.

This could be used to proof that 'something' travels faster than 'the speed of light'.

#### It takes time for A to affect B, even if you can't measure it.

Assuming A and B are different, It takes time for A to affect B, even if A's affect on B is quicker than anything you can measure.

If A affects B (aka B is affected by A) sooner than (distance between A and B) * (1/'the speed of light'), something faster than 'the speed of light' has occurred.

### Intel eggheads put bits in a spin to try to revive Moore's law

#### "between 10 and 30 times lower than CMOS", math???

"and consequently lower power (between 10 and 30 times lower than CMOS)."

10 times lower than a number, say X is X-10*X = -9*X.

Notice the sign, the before has opposite sign of the new. Now are we now gaining power by using this, or was it gaining power before and now it's losing power, or was it zero power change the whole time? or perhaps someone(me?/you?) doesn't understand how this math/power usage works? This doesn't make since to me. What is it really?

Does the same apply to

"low voltage (as much as five times below today's CMOS-based chips)"

5*below a number, say X, is X-5*X =-4*X

#### "between 10 and 30 times lower than CMOS", math???

"and consequently lower power (between 10 and 30 times lower than CMOS)."

10 times lower than a number, say X is X-10*X = -9*X. Notice the sign, the before has opposite sign of the new. Now are we now gaining power by using this, or was it gaining power before and now it's losing power, or was it zero power change the whole time? or perhaps someone(me?/you?) doesn't understand how this math/power usage works?

### T-Mobile goes Apple/Google route by separating phone numbers and devices

#### Blackberry OS computer texting

"Send texts from a computer"

Blackberry OS can already do this. Texting/typing from computer is much faster than texting/typing from a phone. (assuming one can touch type)

#### Re: What's a beeellion?

Shouldn't it be

There's a thousand waspillion in a beeellion.

### Smartphones merge into homogeneous mass as 'flagship fatigue' bites

#### Re: Flappy Bird Syndrome

"1/4 core Athlon"

As if 1/4 core of any CPU would do anything useful without the other 3/4 of the core.

### HP emails personal data of 1,000 CDS workers to 3rd party

"HP emails personal data of 1,000 CDS workers to 3rd party"

First glance of reading the title:

CDS being short for Compact Discs, and skip the word 'workers'.

"Why would HP send 1000 CDs worth of data over email?"

### US feds want cars conversing by 2017

#### This is alot like peer-to-peer bit torrents for cars...

and I thought they hated bit torrent...

### Astroboffins spot HOT, YOUNG GIANT where she doesn't belong

#### Re: and now for some math...

I suppose that could count as a star too... I should have said excluding the Earth's sun, or something like that...

The Earth's sun is ≈ 1/278896.8645 = 1/((4.2421 ⋅ lightyear) ∕ (8 ⋅ lightday ⋅ (lightyear ∕ (365.25 ⋅ 24 ⋅ 60 ⋅ lightday)))) times as far as the next closest star from Earth.

Counting this sun as a star, and 1 AU as the distance between the Earth and it's star, the sun.

"Astronomical unit, an approximation for the average distance between the Earth and the Sun"

http://en.wikipedia.org/wiki/AU

// Qalculate

AU⋅13242⋅day/(127.03⋅AU) = (astronomical_unit ⋅ 13242 ⋅ day) ∕ (127.03 ⋅ astronomical_unit)

≈ 9.00660316460679 Ms

≈ 9006603.16460678579863 s

≈ 0.285402031986171 year

// TI Voyage 200

_au*13242*_day/(127.03*au)

Qalculate, TI Voyage 200, and Wikipedia, use different values for AU

149,578,706,600 m, Qalculate v.0.9.7

149,597,900,000 m, TI Voyage 200 OS Version 3.10, 07/18/2005

149,597,870,700 m, http://en.wikipedia.org/wiki/Astronomical_unit (the same day as this post)

(looks like the TI Voyage 200's AU is a rounded version of Wikipedia's AU, and Qalculate's AU uses a different measurement)

#### and now for some math...

(If something is wrong with this, please correct me)

Given:

127.03 AU approximate distance traveled so far by Voyager 1

4.2421 ly is the approximate distance to nearest star from Earth

Find:

How long would it take at Voyager 1's average speed so far, to go the distance of Earth to Earth's nearest star?

Approximately 76568 years. Last digits maybe off due to rounding, etc...?

Although, I got 76576 years from Qalculate with units, and 76566 years from Ti Voyage 200 with units.

// Research:

127.03 AU is approximately 0.7336640935983627 light days

127.03 AU is approximately 0.002008662816152567 light years

From September 5, 1977 to December 7, 2013 is 13,242 days

// Using Qalculate without units:

p.s. for those who want more digits in light days for my calculation...
