Real or Virtual?

Real or Virtual?

Jun 18 2010 | comment(s)

A physics professor was telling me yesterday that her daughter was having trouble understanding real and virtual images formed by lenses.  That was until she showed her a real image being formed on a sheet of paper by a (spectacle?) lens.[1]  The curriculum (which you all must follow or you will be sent to the salt mines!) only included ray tracing.

And this was at a “good” school.  It seems that our teachers are being frustrated by the production of all these “Jobs for Little Stalins” (of which Britain has so many) that our educational bureaucracy has contrived over the years.
[1] I have had to make a correction here: at first I thought the teacher made a five-minute “Great Escape” from the jam-packed curriculum, and did the demonstration.

Since I do educational outreach programs with living Arthropods (referred to below as BUGS!), I have to actually have bugs. Some people think that’s weird. I’m okay with that. I don’t imagine many would find it surprising that I have always had bugs – or something. I mean Bluegills in the basement bathtub, countless beetles and caterpillars and butterflies in nets and other random containers, tons of rolly-pollies and fireflies… you get the idea. I mean, I drove my Mom nuts! 
What is metahypothesis?

What is metahypothesis?

To give a link in another topic, I shortly cover the meaning of not so common, but very important term - metahypothesis.

Metahypothesis is formed by a number of other hypothesis - when you take some hypotheses and put them together, you get metahypothesis.

Lets look an example.

Assume that we consider two hypothesis - that A is two times B and that A is three times B. We think that they are both considerably strong hypothesis.

Thus, we will form a metahypothesis. It contains the following formulae:
A = (2 + C) * B

Where C is a constant variable. It's a variable on metalevel, with allowed values 0 and 1. It's constant on normal level. We can also use conditionals in case some variable completely changes the case.

A Glossary of Alternative Reality  #1


If you analyse deliberate disinformation deeply - and manage to retain your sanity - you tend to observe some fascinating nuances and psychological tricks.

A bonus in such analyses is the discovery of things which - expressed in deliberately non-scientific terms - are quite amusing.

In an alternate reality, you might find definitions like mine in a dictionary or glossary.

In team sports it is often difficult to determine the value of an individual.   Some sports can do it easily enough, like baseball(1) or basketball, but during the World Cup, casual fans who hear commentators talk about the quality 'form' of a player are lost when the game is 0-0.

Jordi Duch, Joshua S. Waitzman and Luís A. Nunes Amaral of Northwestern University say they may have an answer.
