Practical Projects Update - 12

This is a Podcast on an exercise walk, so it is really limited in terms of quality. I am sorry.

It seems that after a bit of fiddling I have struck on a high Q (low loss) stable pendulum to pick up the spin of electrons. It is really low tech humble shed work.

I also frame this is a strategy of how to build ideas in isolation and understand the culture gulf. I think you have to be more disciplined than you would be in an institution as there is no inhouse levels of disclosure as you work towards a goal.

I chat about an integrated strategy system.

Chasing the Sun 26

Well this is full of interesting information. 'Asia' means sunrise in Sanskrit. I think you would have to say the Ancient Regime of Louis 14 was utterly utterly mad. It is a bit profound really. I really liked finding out that gold is concentrated in hair, and how people were bottle blonds in ancient times. A review of Alexander the Great's hair show that it was blonde more in legend rather than any definitive source.

Pendulum tuned to torsion

Part of the deal is mixing rehab exercise with Podcast. So you will hear me walk to Glenbrook gorge at 8 pm. I look at the next railway works, go down the gorge and then get wet on the way back.

Fairly standard chipping away at problems. The original Einstein de Haas quantum antenna experiment was the size of a large microwave with the torsion pendulum suspended like a mystic pendant. Now I have got the to higher frequency thanks to computer control and smaller by converting it to a conventional pendulum. In the hours since the podcast I now have to get my hands on sapphire jewel bearings as it is really high Q for about an hour then wears down. To my misery I find that you can only order these things by the thousands, and watch making is dead in this country.

Hang in there kiddo, the scientists are coming painfully solving one problem at a time.

Chasing the Sun 25

This looks at using Solar energy. I am really surprised by how early the first applications were. From this perspective president Ronald Reagan is a really monster. In general our intrepid research has not picked the recent rise of solar. I am not so impressed with the science on this one.

Horizontal Einstein

Driving, Podcasting and thinking leads to a pretty bad podcast. However you can listen to me actually think through a redesign. I have just put it together and it is the way to go. It turns it from a top-loader to front loader. I have it baring on two scalpel blades, that I now realize have to be points.

Perhaps there is insight in there into working through the complexities of working through equations and materials and then having to innovate in you garden shed.

Chasing the Sun 24

This goes through the muddled history of time zone and the emergence of GMT and UTC. I have heard the story before, so on one hand it was refreshing but on the other I can see it has little significance to people born this millennia. I felt the Atomic clocks in Jumbos actually did give me new information as I did not get previously that one was flying with and the other against the earth's rotation.

In general I am not that happy with my standard of reading given I have put so much energy to improving.

Notes for Simon Fleming

I sent Simon (my boss in the mid 90's) the basic equations for angular sensitivity of an Einstein de Haas pendulum. It has an insanely small rock as the spin of the electrons are flipped in the changing magnetic field. To be truer to S2 symmetry of the electron it would be more accurate to say pulled through itself. Now looking at all the stiffness and Resonance Q coefficients Simon suggested PMA or perspex that they can draw in any shape. As I have boosts in sensitivity from various sources high Q and open to every mode of excitation is not so attractive. So in this I walk through using a thin walled cylinder. This is in the right direction as I track down loses. Since podcasting this I have fiddled a few equations and am testing the next ideas now. So it is out of date to send to Simon at USYD but it is a record of a bloke having ago.

Practical Projects Update - 11

This is a run down of progress switching to Arduino H bridge technology and angle sensing.

I employ fishing tackle to make a new ferrite sample.

There are a few random conversations with people I meet during the walk

Chasing the Sun 23-1

Really good article on sun dials. It seams obvious that inclining the gomon as it is probably misspell so that it points directly at the sun reduces the noon day sun. I love the fact that the striking of the clock in Julius Caesar is similar to the wrist watch in Ben Hur.

I like the fact that rich people had jeweled sun dials and Charles the first gave his sun dial away before he was chopped.

Chasing the Sun 22

This looks a navigation with the sun. I can fill in the gaps of the polarizing crystals, and the re-imagnitization of Moby Dick's compass but it would be much better with diagrams to aid understanding. It is interesting that Greenwich was selected after a Washington conference and that Plain sailing refereed to the Plain of a flat map. Also the detail of the Metacor projection and what that means is welcome insight
