In your interpretation of quantum physics, do objects have their properties well defined prior to and independent of measurement?

By James Dacey

Facebook poll

Last week my colleague Hamish Johnston wrote about a fascinating survey carried out recently in the quantum research community. Physicists, philosophers and mathematicians were asked to give their responses to a series of questions about the foundations of quantum mechanics. Topics covered aspects of the subject from Einstein’s views on the topic to the prospects of a practical quantum computer. The survey is described and analysed in this accompanying paper posted on the arXiv preprint server.

Perhaps the most fascinating outcome of the survey was the extent of variation in responses to the questions about interpretations of quantum mechanics. This is perhaps surprising given the fact that the modern theory of quantum mechanics has been knocking around now for the best part of a century.

Perhaps it just goes to show how many of the key concepts at the heart of this strange theory are still strong sources of debate for physicists. In this week’s Facebook poll we thought it would be interesting to ask you one of the questions from this recent poll:

In your interpretation of quantum physics, do objects have their properties well defined prior to and independent of measurement?

Yes, in all cases
Yes, in some cases
No
I’m undecided

In last week’s poll we asked you a question about the mechanism by which fundamental physics research is transformed into commercial products. We asked you whether you think patents are hampering the commercialization of graphene. The question was motivated by the publication of a new report from the intellectual-property consultancy CambridgeIP, which suggests that the UK might be losing out in the quest to commercialize this material. 78% of respondents said “yes” it is being hampered, while the remaining 22% said no.

Thank you to everyone for taking part and we hope to hear from you again this week.

  1. Energy is that which changes the position or distribution of mass and mass is that whose position or distribution is changed by energy. In other words, without a net energy, mass remains undisturbed and energy is observed only by its interaction with mass. The randomness of their distribution and interaction and creates the uncertainty in measurement because strong, weak, em, radioactive disintegration and gravity have distinct functions and can sustain the universe only collectively. They are additive within the same class and coexist with other classes. This gives the uncertainty because we measure only one effect at a time and ignore the others that affect the same mass.
