“Being able to direct sound is useful in many situations. Two examples are at a museum where people standing in front of two different exhibits can hear two different commentaries or at home if you don’t want to hear the crap someone else listens to.
This is where modulated ultrasound comes to the rescue – the ability to direct sound with an impressive 5 – 10° spread – that’s unheard of with any traditional loudspeaker….”

“A close look at Neanderthal dental records has shown that the ancient humans used a plant-based “aspirin” to treat pain and illness.”
That was around 180,000 years ago and the leaves they were chewing did actually contain the active ingredient in aspirin..
Evidence of opium use has been found in humans since 4300 BC apparently.
Then there was the small matter of the American Civil War and use of morphine on the battlefields for the first time..
that Neanderthal was chewing poplar tree leaves which contain the pain killer salicylic acid (the active ingredient of aspirin)
A man suddenly finds himself walking along a highway in the southern US, not with the classic missing time of a few minutes/hours, but instead with NO memory whatsoever of his whole previous life, name, childhood, in fact NO memories at all from before the point he finds himself walking along the road!
If this is a real story, then surely higher powers are the ones who brought this about, for whatever reason they had ..
What we really need is “How to upload GOOD programs to iPlayer” lol meh..
Anyway I don’t watch TV anymore myself. I prefer listening to my ever-growing collection of MP3s although I will say that the BBC have done some brilliant nature documentaries which I mind myself looking forward to watching when on nightshift and all quiet..

“Henry the Hoover, with his cheeky smile, is now 36 years old. Developed in 1970 by Chris Duncan – the same man who runs the company today – this iconic vacuum cleaner has long been one of the most popular brands for commercial use, and is now also found in homes across the world.”
“…Mr Duncan’s company, Numatic International, began by making commercial vacuums that were used for cleaning boilers. By 1981, these specialist, tough gadgets had slowly evolved into the smiling, red machine that we know today.”
“…The company is working on the next generation of vacuum cleaners: a cordless Henry. “There are lots of small cordless vacuums out there but we think this is the only big cylinder vacuum in Europe to go cordless,” says Mr Ernill. ”
“…Numatic makes all its vacuum cleaners at its Somerset factory, resisting the temptation to outsource production to cheaper territories. This helps the company maintain the quality of its products. “There’s a lot of affection for Henry, and that affection seems to be passed down through the generations,” says Mr Ernill. “But that would quickly disappear if we lowered the quality of the build.”
“…One of the major challenges that Numatic faces is also its greatest strength: Henrys rarely break. “People know it will last a long time,” Mr Ernill adds. “A customer recently returned one that is 30 years old – it was still working, but is now taking a rest in our museum.”
Numatic always provides spare parts if its products break down, and can retrofit motors right back to the first Henry ever made….”
