Get READY: Scientists set to make TIME STAND STILL tonight

Andrew Newstead

Re: Having a single time is a nonsense

Unfortunately, those of us who are sighted are tied to a diurnal cycle of light and dark, some quite strongly. One of the things recognised recently is how blue coloured light (such as produced in monitors and LCD TV screens) can trigger the wake up response in humans, causing sleep problems for those using screens late at night.

Hola HoloLens: Reg man gets face time with Microsoft's holographic headset

Andrew Newstead

Re: Truely holographic?

This might give you an insight.

http://www.technologyreview.com/news/415755/head-up-displays-go-holographic/

I found this when I was researching holographic HUDs to see if there is any connection to the Holovision. I wouldn't be at all surprised if these people have had a big input to the device.

Re: Truely holographic?

Be careful about dismissing the "holographic" claim here. Current aircraft HUDs have holographic optical components as part of the glass plate that the pilot looks through. They improve the collimation of the devices (allows the user to focus on the outside world and still read the display) and the reflectivity for the plate, thus reducing the power required by the display. One of the things about holographic HUDs is that some of them are curved panels and as such the width of the view is much improved.

It is not inconceivable that this technology has been applied here, it would certainly help with some of the points raised concerning power usage, so describing them as holographic would be an accurate labelling.

Cheers

Re: Idle curiosity

You are right, there is a limit to continued fuelling/defueling but this applies to consecutive attempts to launch. If this flight attempt does not happen today then they will have to wait 3 or 4 days before they try again to allow the rocket's tanks to settle down, I believe that NASA did say Sunday or Monday. Surprisingly Aluminium tanks are fairly forgiving of this kind of treatment and can be used for quite a lot of such cycles before being considered scrap. The main issue would be metal fatigue due to the cycling. This is the problem that did for the early Comet airliners but they have the addition of square corner windows which exacerbated the problem. Once this had been solved we now see Aluminium tubes (airliners) being cycled many times a day without failure and can have cycle numbers going into 10's of thousands.

Trips to Mars may be OFF: The SUN has changed in a way we've NEVER SEEN

Andrew Newstead

Re: Nuclear

>I wonder if the cooling required for nuclear reactors could involve the void?<

Yes, you would use radiators on the shadow side of the spacecraft to radiate the heat into space. Heat management in the vacuum of space is actually quite a tricky thing. With no air or other fluid to take the heat away (like with a CPU heatsink) you have to use radiation and the more heat you generate the larger the radiator has to be. Consequently radiators for a nuclear reactor similar in output to that in a nuclear submarine will have to have a large area, in the order of several hundred to a few thousand square metres, of radiating surface.

This will only be needed for the power generating reactor though, the nuclear rocket engines would be cooled by the propellant (typically hydrogen) being fed into them picking up the reactor heat. The heated (and expanded) propellant would then go blasting out the nozzle of the engine producing thrust and carrying the heat away too.

Hope this is of use/interest

'MYSTERIOUS PYRAMID STRUCTURE' found on COMET beyond Mars: Landing planned

Andrew Newstead

Something more intertesting

The rock (and that's what it is) looks interesting but I'm more intrigued by the smoothness of the rest of the terrain around it. Whole areas of the comet have this smooth melted look, quite unlike any other body we have seen in space so far.

Is it a form of erosion? Dust drifts? Melting?

Can't wait to see what it's like really close up.

SpaceX blasts a mischief of mice, a 3D printer and a cuddly toy* into SPAAAACE

Andrew Newstead

Re: Booster recovery

There were plans to control the stage and manouvure it but it was not equiped with legs so I think a landing test was not being considered for this flight. Bear in mind the first time they tried to land a stage it had no legs and went into a spin that destroyed it. It was thought at he time that the legs would act as fins to stabilise the rocket during it's descent and this seems to have been borne out in the subsequent attempts.

Airbus developing inkjet printer for planes

Andrew Newstead

Re: Silly idea

SpaceX have recently been testing a small rocket engine whose thrust (combustion) chamber has been 3d printed. The comments were that they had been able to make a hugely efficient engine because the component's shape was able to adopt a more sophisticated and complex shape that would be difficult to fabricate using typical "metal bashing" techniques. On test the engine has performed very well indeed.

Rockall batters plucky Brit adventurer

Andrew Newstead

Re: Just how inedible are seabirds really?

Er - no. One of the reasons that this islet keeps being occurpied is that this maintains a claim of British sovereignty to Rockall and the waters between it and the mainland and all that implies (fishing rights, minerals, etc.). So the RSPB might have something to say.

Apple SOLDERS memory into new 'budget' iMac

Andrew Newstead

Re: Very acceptable....

All these comments about fabois are based on the assumption that Apple fans buy everything and anything with the fruity logo, not always true though. Apple have had it's share of non or slow sellers too you know. The iPhone 5c recently comes to mind.

Besides, the true fanbois will be after the more expensive, top of the range kit, you know, the stuff people like me buy second hand after a few years when the next shiney comes out. I don't think I've bought a new computer in the last 15 years and they have all been quite capable for the time.

Spotify boasts 10 million paying subscribers ... Um, is that all?

The Physical option?

I must admit I still prefer my music on a CD. I do use a digital player when I'm away from home but it's copies of my disks that are loaded onto it. I like to have disks as my master copies and make the digital ones I need. I also like the better quality sound I get from the disks when played on a good CD player.

I don't think I'm alone in this.

50+ crowd are wolfing down tablets: Silver foxes are even migrating to the Twitters

Andrew Newstead

It's enevitable really...

If you think about it the first wave of (modern) IT users will be starting to creep into this category, those of us who cut our teeth on Commodore PETs and Apple 2's. We're now moving to pensionable age, certainly can be Saga-louts.

As this generation moves into old age all of the clichés of age being a barrier to technological competence will become not true (if not actually redundant), and this is only going to accelerate from now on.

It won't be long before we see our first middle aged "digital natives" (someone born into the IT age).

Greg Christie to leave Apple as Jonathan Ive seizes design reins

Andrew Newstead

An excellent analysis. I have been using IOS7 since it's release and, apart from a short period of adjustment at the start, I have to say I have no complaints. I'm not an artist or designer so I can't offer any informed comment on design but I mostly find the UI to be quite unnoticeable in use, which I should think would surely be the aim of UI designers.

Re: Seems amazingly cheap

Just done a quick check on Space.com and it reports that the money is to start the planning process for a mission that may launch in 2025. The final cost for such a mission would probably come in at about 40 Billion over 10 years.

I think this fantasticly exciting. If we can put a signal into a nerve imagine an electronic bypass system that reconnects a broken spinal column.

If I was a tetraplegic I would voulunteer for experiments like a flash. Even it didn't work it would be valuable to know and an honour to take part.

Re: Harvesting spare static electricity

The piezo electric method could be the way using the motion of a blink. This would compress the circuit regularly, generating a smidgin of power and a capacitor in the circuit could store and smooth the power pulse into a current.

Apple iWatch due in October 2014, to wirelessly charge from one metre away – report

Andrew Newstead

Re: iWatch ? I cannot believe

Wristwatches came in because pulling a pocket watch was too much hassle in a busy environment. Pulling a phone out my pocket is just as inconvienent when I'm busy and I think a lot of people find that. I don't use a chonograph (not even digital), just a plain "old-school" watch that shows the date as well as time. Much more convienient than fumbling in my pocket and pressing buttons to find out the time or date.

As for "tech-watches", not my cup of tea but who knows.

Re: Moving South

Iceland sits at the "pivot point" of the Mid Atlantic ridge, the line of tectonic sea floor spreading that's pushing America away from Africa and Europe. Esentially Iceland is being split apart so it's volcanoes are being caused by a different mechanism.
