Does quantum mechanics carry the seeds of its own destruction?

The late John Bell considered that quantum mechanics was centrally flawed and ''carries within itself the seeds of its own destruction'', although acknowledging it as a powerful theory. The author discusses what this means and whether it is true. The manner in which quantum mechanics is formulated is at the centre of the debate. It is not, Bell argued, formulated in a logically precise manner. At the heart of their differences is the problem of measurement in quantum mechanics. (UK)
