Magnetic deviation – compass and diving

Magnetic deviation is the error induced in a compass by local magnetic fields, which must be allowed for, along with magnetic declination, if accurate bearings are to be calculated.

So it’s a good idea to hold the compass and the torch in different hands !

Duck test

“ From Wikipedia, the free encyclopedia

For the use of „the duck test“ within the Wikipedia community, see Wikipedia:DUCK.

The duck test is a humorous term for a form of inductive reasoning. This is its usual expression:

If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck.

The test implies that a person can identify an unknown subject by observing that subject’s habitual characteristics. It is sometimes used to counter abstruse arguments that something is not what it appears to be.“

The real ebook experience – Kindle from Amazon

I’m starting many approaches to start reading more of my  books on an appropriate reading device. Unfortunately there wasn’t good hardware out there for me until now. I ordered the new Amazon Kindle for just 99 € and it’s really the eBook reader of choose in my personal opinion. It’s small, lightweight and had a nice price.

The iPad is too heavy and other hardware isn’t exactly what I want to have. The Kindle is still a must buy!
