C Library
C Library How to convert your functions in C into a pre-compiled library. A step by step example using CodeBlocks.
CodeBlocks
Using an IDE (Codeblocks) to write code Instead of writing programs in a notepad and compiling and executing command-line, we are going to learn how to use an integrated development environment (IDE). In that we can compile the program easily, as well as run it step by step for debugging. We will use Codeblocks for this purpose.
Sustainability
Energy Transition and Sustainability
Remake of the C-iasoS conference talk of 13 November 2023. How the United Nations Sustainability Agenda (Agenda 2030) will lead to eradication of humanity.
Science is dead.
                    Long live Science! Science is dead. Long live science! The history of science. Why where and when it died. And why it will recover.
Empirical Forecasting 1/2 Empirical Forecasting. Part 1/2 Empirical forecasting is using past (only) data, without a physical model, to predict the future. Here it is shown that it will lead nowhere.
Empirical Forecasting 2/2 Empirical Forecasting. Part 2/2 Empirical forecasting. In this video a linear trend extrapolation and correlations are discussed. They suffer from the same problem; when done on past data only, without a physical model, they lead nowhere.
Psychology of Climate Change

Pinatubo Pinatubo. How contemporary climate signals are explained by Henry's Law The eruption of Pinatubo in 1991 changed the dynamics of carbon-dioxide in the atmosphere. We also see how after ocean-warm years (El Niño) there is more CO2 in the atmosphere and after cold years (La Niña) there is less. These are all tell tale signs of Henry's Law in the system.
Greenhouse Effect Henry's Law. CO2 in the Atmosphere. Correlation, delay and feedback Explaining Henry's Law, where CO2 in the atmosphere is caused by temperature. Looking at contemporary and historic data.
Greenhouse Effect Greenhouse Effect of the Atmosphere The greenhouse effect explained. Removing some myths (such as that a greenhouse works on the greenhouse effects and that CO2 is the principle climate actor).
Work=Energy Energy Theory of Value. Work = Energy! The Energy Theory of Value. Here it is explained why energy and work are the same things
Residence Time vs.
                    Adjustment Time
Residence Time vs. Adjustment Time of Carbon Dioxide in the Atmosphere
PART 1
We study the concepts of residence time vs. adjustment time time for carbon dioxide in the atmosphere. The system is analyzed with a two-box first-order model. Using this model, we reach three important conclusions: (1) The adjustment time is never larger than the residence time and can, thus, not be longer than about 5 years. (2) The idea of the atmosphere being stable at 280 ppm in pre-industrial times is untenable. (3) Nearly 90% of all anthropogenic carbon dioxide has already been removed from the atmosphere.

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
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.
