News from the world of science is that quantum physicists are no longer too sure of Heisenberg's Uncertainty Principle.
It's confusing when you can't be certain what you're unsure about.
This uncertainty principle, as you know, states that it is not possible to take measurements of anything without causing disturbance to it.
Basically, if you're trying to size up a toatie particle the whole mechanics can be spoiled if you so much as breathe or shine a light on it.
Now quantum physicists at Toronto University have gone over the ground again, implementing weak measurements and using cluster state quantum computing.
Which means they hardly disturbed the photons at all and got results that showed the uncertainty principle is far from certain.
Many readers will be inspired by this debate in quantum physics to undertake further reading, perhaps examining the rift between Einstein's intuitive and Weisenberg's empirical approaches.
My advice is don't bother. I studied a bit of physics at university and it is far too sore on the head. Go for botany or woodwork instead.
You could study physics for ever and never get to the bottom of it. Like those scientists who spent years down the Hadron Collider looking for the Higgs particle. They said they found it. But, as we know from the Uncertainty Principle, it may not be the right size for the God particle. It may well be a crumb off some physicist's sandwich. Now they want to build a bigger £50 billion collider.
Surely the best place for physicists to study the time-space continuum is on the number 90 Glasgow bus. You get on at Partick bus station and go in a big circle taking in most of the sights of the city. Nearly two hours later you arrive at Govan bus station which is less than a two-minute ride away from Partick on the Underground. How's that for an uncertainty principle?
The physicists may find some time-related certainties on the 90 bus. One woman passenger is bound to say: "This is me since Sunday." Or, "Ten o'cloak an no a dish washed."
The number 90 passes, handily, quite close to the Glasgow Science Centre.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
