Quantum mechanics deals with the behaviour of small particles such as electrons. This turns out to be important for engineers when they deal with semiconductors. That's how I got in touch with this exotic subject myself when making my master's thesis in 1988.
Quantum mechanics leaves no doubt: everything is uncertain.
On the one hand, this is a damper on the revelry of science. At the end of the
nineteenth century, it seemed that the world was deterministic and that science
could understand and predict everything. Since then, we have discovered counter intuitive phenomena and uncertainty principles. Schrödinger's cat was no
longer to be found where we thought.
There is also a good side. Quantum mechanics introduces a
certain magic to science. Georges Lemaître's
primordial atom, the idea that quantum mechanics could be at the origin of
our existence, may not make the miracle of being
any less miraculous, but it is already somewhat possible in the scientific
sphere. In quantum mechanics, measuring is really observing. The observer
inevitably influences the measurement he makes. John Archibald Wheeler's
thought experiment even suggests that quantum mechanics plays a role in our
perception of the origin of the universe.
It may be just a dreamy thought, but quantum mechanics seems
to be a scientific basis for love. Just like in love, in quantum mechanics
there is attraction, repulsion, ambiguity and unpredictability. A colleague of
mine once asked me the question: "How can you be so sure that an atom has
no consciousness?". Perhaps the behaviour of small particles is
unpredictable because they have consciousness. Alles
Leben ist eins. But this is not a scientifically based claim.
I also refer to my blogs: "The origin
of time" and "The
nature of light".
