Covid & science
Science in the times of Covid; An alternative hypothesis
This presentation is based on our paper in Research Review, and shows how the Scientific Method -- the basis for science -- was cancelled during the Covid19 pandemic. In fact, the simplest model (by Occam's razor preferred) that Covid19 was a normal corona flu-virus, was never debunked and thus still the correct scientific hypothesis.
Human rights, the economy, the environment and
                    the Covid-19 governmental actions
Human rights, the economy, the environment and the Covid-19 governmental actions
Why the cancellation of democracy and the abolition of Human Rights is not justified by the Covid19/climate crisis
Covid19 Economy Climate
Effects of the Covid-19 Measures on the Economy and the Environment (Atmosphere)
The effects of the Covid-19 pandemic and governmental countermeasures are described in this work by putting it in the framework of the Energy Theory of Value. It is found that the downturn in economy is not accompanied by an equal downturn in energy consumption nor of carbon emissions. Moreover, not even the empirical fifth-power law linking the former two is any longer sustained, more so proving the state of virtualization of our economy (disconnecting it from a physical reality). It is also found that the reduction of carbon emissions had no impact on the dynamics of carbon in the atmosphere, which goes on business as usual. All these results undermine the planned policies of the world agenda.
How to make monto into stereo
Fake stereo effect
How to turn mono sound into something stereo. By adding delay between the channels.

If you take mono sound (L and R equal), but add a small delay in one side, the sound gets a stereo effect. Here I added 8 ms to the R channel after 10 s. And then 8 steps of 2 ms at the L channel after 20 s, so to swap the stereo effect. And then at the end swap back, but slower.

Sound edited with Audacity.

Patterns in random data to make people believe
                    anything ....
Using random data to make people believe anything ...
How humans see patterns in random data and how this can be used to program people into believing things. An example is the song of Lady Gaga, Paparazzi, that, when played backwards (thus random), seems o contain a hidden message. Once you see or hear the pattern, you can no longer unsee it. All new data will then be confirmation of the pattern.

"I Feel Love" on Korg Volca Bass
My first attempt to play something on a musical instrument, ever. It is the base rhythm of the classic song of synthesizer pioneer Giorgio Moroder, "I feel love", made famous by Donna Summer, diva of pop music.
