Re: SKA *isn't* in Australia (or NZ)

I'm well aware *part* of it is going to be in Australia - it's fortunate the engineering capabilities are such that the split isn't going to negatively affect the science aspect, otherwise it'd have all been in South Africa. The significant delay (and resultant "shared prize") was purely to avoid wasting the work done by and in Australia.

In the context of the article, however, it is extremely significant that the vast majority of the project is going to be in South Africa, with satellite posts throughout Southern Africa - a very large area, with very poor land-line internet access and a not-insignificant, relatively evenly distributed rural population, exactly the target demographic for Google Loon. With the to-and-fro over 20Mbps vs (up to) 1Gbps for the NBN, it would seem Australia is not much of a target for Loon, hence my initial point.

SKA *isn't* in Australia (or NZ)

The primary site for SKA is in South Africa, part of sub-Saharan Africa, and the entire region is exactly the type of area Google Loon is intended to provide internet access for. I doubt NZ (or Australia) are one of the primary spots Google intends on deploying large numbers of these balloons - the pilot is probably being done there because of infrastructure and favourable legislation, etc.

The long baseline configuration of SKA in Africa has dishes planned far to the north, in exactly the areas Loons would be most useful. To examine this impact purely from an antipodean perspective is to ignore the main impact of the idea.

In fact, it's unlikely Google would be able to operate this anywhere near Carnarvon, where the primary site will be - the SA government enacted fairly stringent legislation to protect the investment being made in radio astronomy.

Re: Why not use a helicopter?

I believe the density of the air at that height is the limiting factor - helicopters just can't get enough lift to remain aloft. Flying into Everest Base Camp is pretty much as high as they can go.

Blown away...

I don't know if it's journalists keeping a closer watch on scientific papers/press releases, more scientists doing awesome stuff, or that we (science/society) are in a rich run of form for this type of thing, but on a weekly basis there is something new, totally mind-blowingly amazeballs being reported on.

This is one of those moments. The video of Curiosity's descent another. The analysis of Vesta. Pretty much anything Musk does.

I missed the moon landings by 11 years, but where we're going seems even more incredible.

Go Dr Brain!

Dr Brain is the grandfather of a kid I was friends with at school - he's been working on this for years. I remember the setup they had outside the kitchen, where his wife would grind bits of stone into translucent wafers, in which they'd find these things. Diamond grinding wheels, lots of black grime that stained clothes. Awesome for a kid to investigate.

Actually got to see some blobs through a (normal) microscope the one time, but to the uneducated, they didn't look like much.

"Apparently, you can use it as an AC"

I really hope they do work as an aircon too - it's been 35-38C daily in Cape Town for the last few days, and a good number of days overall this summer.

With the missus determined to maintain a comfortable range between 22 and 28C when she sleeps during the day, the aircon in the bedroom is a major drain on power.

Hollywood siren invented key phone tech TRUE

mike 32
Boffin

I only know of bluetooth that uses frequency hopping spread-spectrum, and I don't think it's really a solution for cellular tech.

Direct sequence CDMA is used much more, (ie WCDMA), which is also why 3G battery life is much less than 2G FD/TD multiplexing. Because everyone transmits simultaneously, the receiving tower needs all the incoming signals to be of equal strength, such that closer terminals don't drown out terminals further away. Leads to lots of fiddling with transmission power at the handset, hence reduced battery life.

From what I know, direct sequence CDMA also has it's origins in showbiz, although British, I think. Apparently Churchill and FDR used to chat over lines encrypted by playing a synchronised record over the voice - an inverted signal on the other side cancelled out the added LP, yielding clear speech to the listener, but no-one else.

Disclaimer:

I haven't done any work in this since final year elec eng, but I did get my old Bernard Sklar Digital Communications textbook out as a refresher. If there's any clarification on the invention of direct sequence, I'd be keen to follow any links provided.

I wonder if reversing the aerofoil effect would work?

Since the cars aren't going to take massive corners at speed, altering the aerodynamics to make the car *lighter* at top end speeds could save energy...

I wonder to what degree savings could be made using this?

From a safety point of view though, I'd imagine passing those road trains with a lighter vehicle, and such a big surface area parallel to the road would make it quite susceptible to turbulence.

Amazon fans order three Fires for every E Ink Kindle

I dunno...

I love my kindle - it's a viable replacement for a book, in terms of easy-on-the-eye use.

I'm (only?) 29, but I find I hold my cellphone further away from my face when I look at it, compared to years ago, or younger (teens) extended family members. My eyes are knackered after a day on my laptop without my glasses. A fondleslab would just make all that worse.

I don't have a fondleslab because between my laptop and my bb, I don't have the need to play games, browse photos surf the net or do whatever else people who *still use their tablets six months after buying it* do.

The kindle is a *book* replacement, NOT a crap-screene tablet, and it's damn good at what it was designed to do. I don't see them going anywhere.

Details re the "London Conference"

The comments were made at SATNAC - the South African Telecommunications and Network Applications Conference, an annual conference hosted by Telkom, SA's monopolistic fixed-line operator, known for poor service, overcharging, poor broadband speeds (384kbps is still considered "broadband" here), hosted this year in East London, a city in the Eastern Cape.

RIM, please don't give up our privacy! The ANC has turned evil, and I'll bet this has nefarious intentions.

Further info here: http://www.satnac.org.za/

I presented a paper from my MSc at SATNAC a few years ago - seems a good party was had in general by all except me - hit by a strep throat right after I presented in the first breakout session.

Curved light drives boffin one-upmanship

mike 32
Thumb Up

That is of course, entirely correct.

My grasp of the correct terminology is clearly a bit rusty.

Vector = speed with a direction. Velocity is a vector.

Scalar = speed without a direction. Ones' respective economy/government/Republican Primaries is a scalar.

mike 32
Boffin

Not sure about being too picky, but...

The term "acceleration" is used wrt vectors - the light has both velocity (c), and direction. The velocity remains the same around the obstacle, but the direction changes - and a change in the direction of a vector is termed acceleration, even if the velocity remains constant. A change in velocity without a change in direction is also termed acceleration.

A scalar is like a vector, but without a direction - hence a change in direction of a scalar does not result in acceleration.

I hope that's all correct. It's been along time since first-year physics, but I stumbled over "acceleration" being a change in direction of a vector at first.

I don't have an answer to the question about whether the outer edge of the beam travels faster than the inner edge, will be interesting to get clarity on that point. Maybe the beam velocity remains at c for all points on the curve, resulting in a beam with a slanted leading edge, instead of straight?
