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.
