This may be completely off topic but I thought it was interesting enough to share. Apologize in advance to Wyttenbach that I know he dreads any link from this source, but they now have a sort of academic publication that published this paper
Ancient Measurement an Abstract (The Meter is 5000 year old)Ancient Measurement an Abstract (The Meter is 5000 year old)www.academia.eduIt’s an interesting brief paper that shows how the meter that was “invented” By the French was actually much older and based in pendular motions that are directly related to the size of planet Earth.
I took interest in this issue some months ago when watching a documentary that pointed out that several measurements of ancient monuments are almost perfectly exact in metric units (case in point, The famous H blocks of Puma Punku, which measure exactly 1001 x 1000 millimeters) and also the famous Egyptian royal cubit that is the exact length of an arc made by a pendulum of 1 meter when the period of the pendulum is one second.

The voyage of the research in terahertz (THz) technology has an intriguing application in terahertz detection, and the graphene absorbers have dramatically enhanced the effectivity, and the efficiency in its performance. Though, there is a need of wide angle insensible, polarization angle insensible, broadband terahertz metamaterial absorber (TMA) with reduced design complexity. Hence, in this research an effort has been carried out to develop such TMA with equivalent circuit modelling approach. A massive − 10 dB reflection coefficient (RC) bandwidth of 2.66 THz (1.08–3.74 THz) has been obtained by the proposed TMA device with two significant peaks of − 19.48 dB and − 14.5 dB at 1.32 THz and 3.44 THz, respectively. The oblique incidence stability of the device has been verified by investigating the effect of wave incidence angle, and wave polarization angle in RC characteristic. Further, the physics behind the absorption has been systematically illustrated along with three different absorption mechanism, i.e., input-impedance matching mechanism, wave interference phenomena, and induced current model, that attest the Unprecedented absorption results. Moreover, the electrical parameters of the device (i.e., effective electric permittivity, and effective magnetic permeability) have been extracted to analyze the metamaterial behavior of the device. The results are good enough to explore the potential of the TMA for THz sensing applications.

Laser micro-texturing using ultrashort pulse lasers is a new technology for applying surface textures with very fine features and an extremely high depth resolution. It allows the creation of small-scale textures that change the functional properties of surfaces, like reduction of friction or change of optical properties. The process can be applied on any material and can be used for texturing complex curved surfaces.
Some nice properties / advantages of micro-texturing using ultrashort pulse lasers are:
- Machining of extremely small features of down to 10 µm or smaller
- Very high depth resolution (sub-micrometer)
- Works on nearly every material, including very hard materials
- Negligible heat effects: no melt, burrs, or other damage
- Contact and force-free process

We currently plan to realize a LENR project with < 20nm structures. Still a bit to large. So these Lasers area nice toy only!

Do you seriously think that news of the Pandora papers will be deleted? Maybe this video will be. I haven't watched it, and maybe it is full of nonsense. But the Pandora papers story is in every major newspaper and website in the world. It is not going anywhere.

Posting here this recent video from the Thunderbolts Project channel, it presents us with a very clever and well thought analysis of how Cosmological viewpoints influence all aspects of human endeavor and how positive or damaging that can get to be.

Accelerating Hydrogen Absorption and Desorption Rates in Palladium Nanocubes with an Ultrathin Surface Modification
Hydrogen absorption and desorption in shape-controlled Pd nanostructures does not occur uniformly across the entire nanoparticle surface. Instead, hydrogen absorption and desorption proceed selectively through high-activity sites at the corners and edges. Such a mechanism hinders the hydrogen absorption rates and greatly reduces the benefit of nanoscaling the dimensions of the palladium. To solve this, we modify the surface of palladium with an ultrathin platinum shell. This modification nearly removes the barrier for hydrogen absorption (89 kJ/mol without a Pt shell and 1.8 kJ/mol with a Pt shell) and enables diffusion through the entire Pd/Pt surface.

The case for cold cases - Nature Physicswww.nature.com
"One might guess the subject had become
uninteresting because most of the key
questions had been settled. But that’s not the
case. The more recent studies didn’t find any
confirming evidence for cold fusion, such as
production of neutrons reflecting genuine
fusion events. But they did find that the
initial debunking of cold fusion in 1989 was
possibly premature, as “the relevant physical
and material conditions had not (and indeed
have not yet) been credibly realized and
thoroughly investigated.” Today the area
remains rich in unexplained phenomena
at the edge of what we can reliably study
experimentally.
In other words, the subject isn’t in the
mainstream of current research, but not
for any particularly good reason. It’s out of
fashion. Such neglected areas may well be far
more common than we usually think. In the
scientific process, important matters often
remain unexamined — or worse, get buried
— even as science moves on."
