regarding computing using "magnetic tunnel junctions."
Not vacuum. Chandra Bose used dialectrics thusly years ago.
Superluminal tunneling (faster than light transmission of
signals) was first observed at the University of Cologne
with micro-wave photons. Soon thereafter these experiments
were duplicated and validated at the University of Berkeley
For theoretical physics the implication is that there exist
spaces devoid of time.
Prof. Dr. Nimtz present experiment takes it's inspiration
from an experiment by Jagadis Chandra Bose, an Indian
physicist born in 1858. Bose's successful public
demonstration of remote signaling with radio waves in 1895
predate Marconi's experiments by two years.
In 1897 Bose carried out experiments with semiconductors at
frequencies as high as 60 GHz and was in the opinion of Sir
Neville Mott, Nobel Laureate in 1977, at least 60 years
ahead of his time.
The new experiment of Prof. Nimtz explores total internal
reflection of micro waves inside a dielectric prism, and the
effect and characteristics of a small air gap between two
One known effect of quantum tunneling is the propagation of
photons at speeds much faster than light.
Prof. Nimtz explaining the tunneling effect on the
dielectric prism. The modulation of the microwave is approx.
1Ghz. and has a wavelength of 3cm. The gap between the
prisms is 5cm, and tunneling takes place.
Prof. Nimtz: "The waves enter on the left and are being
reflected totally on the first wall. Only when the distance
between the two prisms is not too great the can signal
tunnel through the gap. It looks as if this gap here is the
When we increase the gap the signal intensity received at
the other end decreases. This has already been shown by Bose
in 1897. But the time in which the signal traverses the
tunnel has not been reliably measured until now."
Speeds measured on this device exceeded 9x the speed of
light, within the frame of reference of this tunnel. The
speed is achieved by the staggered effect of repeated change
from Perspex to air.
Perspex to air. Bose 1897 diagram looks like the prism set-up
that Nimtz uses.
Anyway, any news of new carbon bonding methods or configurations?
More unusual carbons? C82 metalo-bonding?
