Leading zeros are not considered significant figures when they are placeholders used to express the magnitude of a measure, in cases where the magnitude itself is considered essentially certain.

For instance, if you say that the diameter of a €1 coin is 0.0232 metres, it's clear that the leading zeros are placeholders, since it was already obvious that the diameter of a €1 coin is less than 0.1 metres. In information-theoretic terms, the leading zeros don't convey any bit of information.

On the other hand, when you are dealing with estimates where there is uncertainty even on the magnitude, then the leading zeros are significant: If you say that the probability of an event is 0.0005, and it wasn't already obvious that it was less than 0.001, then the leading zeros do convey information.

They convey information, but they are not significant figures, which is a term with a specific meaning.

Finally Ending My Cryo-Crastination

I've finally decided to take the plunge and make the arrangements for my eventual cryonic preservation. To help myself make sure that I actually follow through with everything necessary, I'm publicly pre-committing myself here to accomplish that.

 

As initial evidence that I'm actually serious about doing this, I've sent an email to The Cryonics Institute today, whose contents were as follows:





I have decided to finally stop procrastinating and make the necessary arrangements for my eventual cryonic preservation, and I have chosen CI to make those arrangements with.

I have looked through your membership pages and online sample forms, and I believe that I can work through my end of the paperwork without any real trouble, although I would still appreciate any advice you have to offer. For example, I live in Canada, about an hour's drive from Toronto, which might affect which forms are necessary.

Before I send my initial payment, I would at least like to confirm the basic details, and let you know who the money is coming from. It appears that, to start things off, I can Paypal you USD $110, for the yearly membership fee plus the first quarter's dues; after which I would mail you a physical, signed copy of the yearly membership application. After that, there will be a variety of documents to sign and have witnessed; and the insurance plan to arrange for. Is that a reasonable summary?

For the life insurance, I am thinking of a 20-year term policy with RBC (Royal Bank of Canada). Have you had any dealings with them previously, to know whether or not there will be any problems in setting the Cryonics Institute as the beneficiary? Do you have any recommendations about how large a benefit in excess of the basic USD $35,000 amount the policy should pay out, such as to cover currency-exchange fluctuations or the 'local help' rider?

Is there anything else you would recommend be discussed before I make that initial payment and set the ball in motion?
