Apple iPhone 6 announcement just hours away

Apple's big announcement later today (10 a.m., 09 September US PDT) is universally expected to include the iPhone 6. Both 4.7-inch & 5.5-inch models are expected.

On a personal note: the suggested relocation of the sleep/wake button from the top to the side will represent the loss of the only feature I miss from my iPhone 4.

All the hype:

Carbon fiber wheels cut weight & boost efficiency (video)



Carbon fibre wheels are stronger & lighter to reduce:

● Wheel flex for improved handling & control — see the video above.

● Unsprung weight for improved handling, traction, & ride.

● Gyroscopic torque — see the video above, around the 6:20 mark.

● Rotating mass — a moving object has kinetic energy. In a vehicle, this energy is provided by the motor. Less energy requirement means more distance for the same cost. A lighter vehicle accelerates faster, & is more efficient, because it requires less energy from the motor to increase its speed, & so its kinetic energy. Unlike many other parts of a moving car, the wheels also have rotational energy. Once again, this energy comes from the engine. Weight saved in any part of a car improves its performance & efficiency. Weight saved in a lighter wheel improves performance & efficiency as for any other part of a vehicle, plus reduced rotational energy.

Archer fish shoots its prey (video)

Check out this amazing video of the archer fish shooting insects. Amongst the difficulties the archer fish has to overcome are: refraction at the air/water interface, which distorts the position of the insect; & the the necessary trajectory of the water stream through the air.

And the winner is — Nevada!


Credit: Tesla/Inhabitat

Tesla has been in negotiations for several months about the site of what will be the world's largest lithium ion battery factory. Candidates included Arizona, California, Nevada, New Mexico, & Texas. Cost will be $5 billion, $500 million of which will be provided as incentives from the chosen state.

http://www.teslamotors.com/about/press/releases/nevada-selected-official-site-tesla-battery-gigafactory

Tesla is establishing what has become known as the Gigafactory to push the price of electric vehicles (EVs) down. Price cutting is an aim of all business entities. In this particular case, it has a special purpose for Tesla's Model 3 (formerly Model E). Major design parameters are 200 mile range & $35,000 price point. To meet the Model 3 price point, EV battery price must fall by 30% [1]. Tesla's recipe for this price reduction is the Gigafactory.

Nevada won after a lengthy battle, including claims that California offered to waive certain environmental provisions [2].

To Tesla's credit, a spokesman replied, “It would be completely counter to the mission of the company to go against environmental legislation.” [3]

New "Dreadnought" dinosaur is the most complete specimen of a giant


Credit: Jennifer Hall/Scientific American

Dreadnought represents the most complete giant dinosaur discovered to date. "Giant"? At seven times the size of a Tyrannosaurus Rex, the term seems justified.

Most things that die are soon destroyed. Fossilisation, therefore, is a rare event. Meat is eaten by scavengers, often with bones broken up &/or moved considerable distances. Anything that's left will usually be broken down by agents of decay, such as bacteria & fungi.

Fossilization depends on some relatively rare event, usually involving rapid burial. Something small, say the size of a mouse, can be buried relatively easily. Burial of an entire animal seven times the size of a T. Rex is much less likely. Thus, fossils of large animals are usually more or less incomplete.

How did Dreadnought live? Given its size, it probably had nothing to fear from anything, even a predator like T. REx. Hence the name — dread nought — fear nothing. In feeding, that long flexible neck would have given it access to an enormous volume of plant matter. Modern day giraffes use a similar strategy on a much smaller scale.

Between imperviousness to attack & that enormous neck, Dreadnought probably spent its days planted in one spot, munching its way through all the food it could reach. After exhausting everything in reach, it would have moved a few metres & repeated.

Samsung Galaxy Note 4 announced


Credit: Samsung/BusinessWeek

A few features worth noting:

● Metal/premium construction/premium product/quality feel/etc — Samsung has a record of using less glass & metal than some other manufacturers in its phones. Reviewers have been banging on about this for years. With the Note 4, Samsung has incorporated some metal into the case. One of the reasons I abandoned the iPhone 4 was its fragile glass/metal construction. Have you ever dropped a phone? Is there anyone who hasn't? If I'm carrying hundreds of dollars worth of hardware, that I depend on for a large & growing list of functions, I'd prefer something with the resilience of a basketball. That's not going to happen, but a minimum of glass, & replacing metal with shock-absorbing plastic is a good start. Better is to put it in a case/cover as well, which, fortunately, can make glass/metal/plastic construction moot, if you manage to chose the right one.

● Ultra low power mode lets it run all night on standby mode with only 5% battery.

● Fast charge to 50% — between this, ultra low power mode & the very slightly larger 3220 mAh battery, this thing should never let you down.

● Increased resolution — screen size is unchanged at 5.7 inches, but resolution has been increased from 1920 x 1080 to 2560 x 1440. Attention all mobile phone manufacturers: it is some time since anyone has been able to see the individual pixels in the display of top-of-the-line mobile devices. Enough already! The only practical consequence of further increasing resolution is the negative effect on battery life.

● Front facing camera resolution has been increased from 2 megapixels to 3.7 MP. Focal length has been shortened, increasing the viewing angle to 120 degrees. Although this will let you fit more people into a selfie, increased fish-eye effect won't make them look any better.

● Rear camera — resolution increased from 13 to 16 megapixels & optical image stabilisation added, adds up to better images.

If anyone can get delivery drones legalised, it's Google



Delivery drones have been around, as a concept, for some time. But so far, regulations have been in the way. Now, Google has thrown its hat in the ring.
