*(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) Atomic force microscope can detect slight "atomic force" change.*

Atomic force microscope can detect and **control** very small atomic force change to identify or move each atom.

By attaching various molecules to the tip of probe, measuring actual "*forces*" among different atoms is **possible**.

After knowing detailed forces among atoms, it seems possible to **move** each molecules to investigate and control new chemical reaction.

But physicists **stop** advancing from there ! Because the current quantum mechanics **doesn't** allow us to define "actual" force.

The only tool of quantum mechanics is unrealistic wavefunction which true meaning remains unknown and useless.

*(Fig.3) But Schrödinger equation is useless in multi-electron atoms !*

We have the cutting-edge technology to detect and manipulate each atom. But the old quantum mechanics **prevent**s us from advancing !

Schrödinger equation is the **only** tool to consider atomic behavior in quantum mechanics. We are **NOT** allowed to use other methods than Schrödinger equation !

The problem is Schrödinger equation **cannot** solve multi-electron atoms. They just choose fake approximate solutions from *infinite* choices.

"Choosing" convenient solutions means Schrödinger equation has **No** ability to predict new atomic behavior. This is where our science **stops**.

Whatever **fake** solutions we pick up, it can never be a "true" solution.

*(Fig.4) DFT is one of "false" approximations of Schrödinger equation.*

Density functional theory (= DFT ) is one of approximate Schrödinger equations. DFT replaces electron-electron interaction by **fake** *artificial* potential.

In Schrödinger equation, they just choose fake approximate solutions as "trial wavefunction". In DFT, they just choose "fake artificial *potential*".

There are NO restrictions in choosing these fake potentials. We can choose any forms of these potentials from **infinite** choices in DFT.

So DFT has **NO** ability to predict any atomic behavior. In spite of this, this DFT is the **only** tool for analysing atomic force microcsopy !

No matter how many times they catch slight atomic force, all they can use is useless density functional theory (= DFT, see this p.6 ).

All in these single molecule detections, useless density functional theory is the **only** method to **interpret** each atomic force ( see abstract of this and this ).

This is where out science stops. Physicists are **shackled** to old useless methods which **don't** admit "concrete *force*". It just gives us weird wavefunctions as a tool.

*(Fig.5) We have to admit "real things", real force, real wave field to advance !*

Quantum mechanics **shackles** us to useless wave function. **NOT** admitting any "*concrete*" real concepts such as "real force" and "real de Broglie wave".

Unless we admit real forces, it's impossible to know and compute each atomic and molecular behavior !

The moment we admit real concepts = free from old Schrödinger equation, it becomes possible to manipulate each single atom and chemical reaction.

Controlling chemical reaction means creating "artificial **enzyme**", which leads to clarifying protein's movement and **curing** fatal diseases !
