1
Quantum biology is looking for and studying quantum phenomena, quantum effects inside living cells.
2
On the one hand, physicists don't like applying their laws of physics and quantum mechanics inside living systems because biology is hard,
3
it's complicated, it's messy.
4
It's hard enough trying to find quantum effects in a sterile physics lab.
5
How does that sort of quantum behaviour survive inside the noisy, messy, complex environment of a living system?
6
So physicists think, no, that's too complicated for us.
7
Biologists don't want to think about quantum mechanics because by and large they don't understand the mathematics of quantum mechanics.
8
And to be fair, molecular biology and genetics have progressed very well, thank you very much, without any help from quantum mechanics.
9
In the middle, between the physicists and the biologists, are the chemists who say, well, of course, once you get down to the level of molecules, you're going to hit the quantum realm at some point.
10
So you shouldn't be surprised that there must be some quantum effects.
11
Don't go inventing new fields of science just to make it sound sexy somehow.
12
There may be quantum effects going on, but that doesn't play a functional role.
13
You don't need that to explain how an enzyme catalyzes a particular chemical reaction
14
or how bacteria photosynthesizes light and turns it into chemical energy.
15
That's all biochemistry and it's all understood.
16
My counter argument to that is that it may well be that there are quantum effects.
17
For example, quantum tunneling when a particle can jump from A to B in a way that's forbidden in our everyday world, but which is very familiar to us in physics and chemistry,
18
that may well play a very fundamental role in certain biochemical processes.
19
For example, whether mutations can take place in DNA because a single proton,
20
a hydrogen atom, has jumped from one strand of DNA to the other in a way
21
that it wouldn't do if we didn't use the rules of quantum mechanics.
22
Now this could happen if it's given enough energy by say the surrounding water molecules
23
that can nudge it over but it can also quantum tunnel across
24
which means it can jump even though it doesn't have enough
25
energy to get over the energy barrier they can quantum tunnel
26
through the hill like a phantom walking through a brick wall
27
now mutations are necessary for life otherwise there will be no change given the current progress we're making in genetics,
28
gene editing, in being able to manipulate the building blocks of life down at the molecular scale.
29
If quantum tunneling plays an important part,
30
might it be possible to inhibit certain mutations by inhibiting the ability of particles to quantum tunnel?
31
That would suggest that quantum mechanics plays a role in the entire evolution of life on this planet.
32
And that might have huge implications for our health.

Was ist die Shadowing-Technik?
Shadowing ist eine wissenschaftlich fundierte Sprachlerntechnik, die ursprünglich für die professionelle Dolmetscherausbildung entwickelt und durch den Polyglotten Dr. Alexander Arguelles populär gemacht wurde. Die Methode ist einfach aber wirkungsvoll: Du hörst englisches Audio von Muttersprachlern und wiederholst es sofort laut — wie ein Schatten, der dem Sprecher mit nur 1–2 Sekunden Verzögerung folgt. Anders als passives Hören oder Grammatikübungen zwingt Shadowing dein Gehirn und deine Mundmuskulatur, gleichzeitig echte Sprachmuster zu verarbeiten und zu reproduzieren. Studien zeigen, dass es Aussprachegenauigkeit, Intonation, Rhythmus, verbundene Sprache, Hörverständnis und Sprechflüssigkeit signifikant verbessert — was es zu einer der effektivsten Methoden für die IELTS Speaking-Vorbereitung und reale englische Kommunikation macht.
