*(Fig.1) ↓ This microscope can observe and manipulate each single atom.*

Using atomic force microscopy, we can observe and manipulate each single atom. So we have a cutting-edge technology to **control** the smallest particle.

In spite of these useful technologies, why **cannot** we manipulate each atomic behavior to cure fatal *diseases* such as cancer and HIV ?

In fact, old basic theory **prevent**s us from advancing !

*(Fig.2) "Mechanical force" atmong atoms can pick up a single atom.*

Like machanical force among things, even atoms repel each other as their distance is closer. These forces can be measured by atominc force microspopy.

Using these **repulsive** *forces* among atoms, we can make "atomic **tweezers**" which can pick up a single molecule. ( this is different ).

Realizing atomic tweezers controlling each single atom means we can make any artificial nano-molecules and enzymes to *cure* fatal diseases.

But in the current science, old quantum mechanics (= Schrödinger equation ) is the only option to deal with atomic interaction.

The problem is this quantum mechanics has **NO** realistic concepts such as "force" and "moving electrons". It makes atomic tweezers **impossible**.

Its "vague" electron cloud models **prevent** us from *formulating* and using real atomic forces !

*(Fig.3) Quantum mechanics cannot deal with multi-electon atoms.*

To realize atomic *tweezers* controlling a single atom, the first thing to do is **formulate** each atomic force.

But quantum mechanical wave function **cannot** define actual force, because it does not admit electron's mechanical motion.

Instead, quantum mechanics argues each single electron exists in **many** places at the **same** time in parallel worlds !
← nonsense.

Now, Schrödinger equation is the **only** option for deal with interatomic behavior. But it has NO exact solution in multi-electron atoms.

All they can do is **choose** fake trial function ( this p.2 ) as multi-electron solution. We can choose **any** form of *fake* solution from *infinite* choices.

So quantum mechanics cannot predict multi-electron atomic behavior.

They say Pauli exclusion repulsion is caused by antisymmetric wave functions. But they **cannot** find those exact wave function in multi-electron atoms.

As a result, quantum mechanics has **NO** ability to formulate real force using its (fake) wave functions and Pauli exclusion.

*(Fig.4) Introducing real electrons' motion, real de Broglie wave is essential.*

We can measure each atomic force using atomic force microscope, but quantum mechanics **cannot** *formulate* these forces using 'concrete' models !

The first thing to do is introduce **real** and simple atomic models. Quantum useless wave function **cannot** *separate* each single electron.

So in Schrödinger equation, two electrons **cannot** avoid each other by Coulomb repulsions in the simple way, which makes it very hard to formulate atomic force.

Not only Coulomb forces but also de Broglie wave is necessary to estimate each atomic **radius** ( atomic radius is longer as 1, 2, 3 × .. de Broglie wavelength ).

Interference among electrons' *de Broglie* waves can explain well about Pauli exclusion force and valence electron number.

Quantum Schrödinger equation does **NOT** admit *real* de Broglie wave, so it **cannot** estimate actual atomic radius.

So under **vague** quantum wave function (= fake solution in multi-electrons ), it's **impossible** to formulate actual interatomic force and atomic tweezers.
