Congratulations! You just reinvented the reflector!

Congratulations! You just reinvented the reflector!

For half their research grants I promise to reinvent the director within a month...

For those not familiar with RF: This has all been known for a long time. Just look at the Yagi Uda antenna (your terrestrial TV antenna):

Reflectors have also been known in all kinds of shapes and it is well known that beams are shaped by reflectors. If you look at a satellite dish, the dish is the reflector. You may also have seen TV antennas with a vertical mesh at one end, or one that is V-shaped.

So, this is not new at all. What it however is in many countries is illegal, because there are regulations regarding the field strengths created by WiFi or other devices. Focussing the radiation into a beam will exceed that field strength in certain areas around the antenna (within the beam), which is often not allowed.

So, congratulations... And if someone has some research funds to burn, I'll gladly be of assistance...

Oh bread

For you too...

Dammit, Janet, that's a tasty Monday morning bread...

A comic convention was deemed blasphemous in the Libyan capital, Tripoli, where an Islamist paramilitary group shut down a gathering of superhero fans for "inciting violence," detaining and reportedly beating some 20 participants.

So they were accused of inciting violence, an offense for which they had to be beaten - right... Boy, are they lucky that they have freedom and democracy now!

Yesterday the park was full of pupils (elementary school?) who were busy sweeping leaves from all the paths.

Yesterday the park was full of pupils (elementary school?) who were busy sweeping leaves from all the paths. They had sectioned all ways and marked the sections with chalk. Just when I went through with Nimrod, many pupils were happily reporting completion to the teacher in their section.

Well, just good they are only coming once a year and don't check again the following day, that could be bad for morale - because this is how things looked the following day...

14kg gingerbread, at least this problem is out of the way. Stollen next?

14kg gingerbread, at least this problem is out of the way. Stollen next?

So that's 7kg of gingerbread, today's work.

So that's 7kg of gingerbread, today's work. (I keep 1kg dough for my students to play with.) Of course I can't leave it this way, not only can I not close the box, there is now too much pressure on the pieces at the bottom. The pieces are hard now, but will become soft within a month, so I need to spread them.

In the foreground I've already mixed all "powders" for the next batch. And now I need to give my QA assistant some more work...

It's time again...

It's time again...

It is still a while, but I made the first marzipan potatoes this year with students.

It is still a while, but I made the first marzipan potatoes this year with students. What was that film title? "Gone in 60 seconds"? Apparently nobody around had eaten something like this before...
