Breaking Bad began with an amazing premise: what if a man with nothing to lose had to leverage whatever skills he had to make the most money in the shortest possible time? Walter White was a chemistry teacher with a mind for science and cancer that was going to eat him alive. He turned to cooking meth to earn as much money as possible before he died, pairing with an ex-student who had a few connections in the criminal underworld.

"You and I will not make garbage," White tells Jesse Pinkman, his childlike partner, after raiding the high school's chemistry lab for supplies. Quality is as important to him as purity would be to any professional chemist. "We will produce a chemically pure and stable product that performs as advertised. No adulterants, not baby formula, no chili powder," he says, introducing his partner to the correct types of flasks, beakers, and equipment for the job. He points out that they will have an emergency eyewash station, to the dismay of Pinkman. Two things become clear: White suffers from barely hidden rage about his situation, and he is a huge geek.

The first batch of product they create together sends Pinkman into spasms of joy, and everyone who smokes the meth in the opening episodes is astounded by the quality. "You have crystals in here two inches, three inches long. This is pure glass," Pinkman says in awe. "You're a goddamn artist. This is art!" White replies that it's just basic chemistry.

The pattern is set in these opening scenes. White gets to his lofty position in the later seasons due to his ability in chemistry, and the first few episodes feel like love letters to knowledge of chemical reactions. Most of the dangerous situations the characters find themselves in are solved due to White's knowledge of chemistry and science. In one tense standoff he creates a bag of mercury fulminate that looks like meth, and uses it as a bomb to back a drug kingpin into the corner.

Later the duo has to deal with the disposal of a body, and Pinkman appeals to White's knowledge of science to solve the problem. "It seems to me our best course of action would be chemical discorporation," White says, and he gives instructions for Pinkman to pick up a polyethylene tub to hold the body. This seems silly, since "any decent acid" would eat right through the plastic, according to the young addict, so he simply places the body in his bathtub, along with a gun and a healthy amount of hydrofluoric acid. The result is one of the most shocking scenes in the first season.

"That stupid plastic container I asked you to buy? You see, hydrofluoric acid won't eat through plastic. It will, however, dissolve metal, rock, glass, ceramic... so there's that," White says after that moment. In the opening scenes of the next episode the two have to mop up the chemical remains of the acid-soaked corpse, while White reminisces about the time he and a colleague broke the human body down into chemicals and percentages on a blackboard as a thought exercise. These situations and scenes pepper the early days of the show, as White creates thermite from the aluminum powder found in an off-brand Etch-a-Sketch, or he extracts ricin from Castor beans to use as a poison.

When the two are up against the wall and need to produce more meth without pseudoephedrine, White simply creates a new recipe for the drug. "Yay, Mr. White!" Pinkman yells. "Yay, science!"

In one scene, White creates a galvanic cell to jump start their stranded camper after a bad day out in the lab. Walter White proves time and again how powerful science can be, acting as a sort of meth-cooking MacGyver.

The science is rarely true to life in a way that can be replicated; mercury fulminate is actually a powder, and would be tricky to transform into a crystal that looks like crystal meth. It's also incredibly unstable. "As in don't touch it, don't expose it to light, don't mess with it unstable. It can be detonated by sparks, shock, friction, or even a wayward glance," a chemist wrote on ScriptPhD. "Realistically speaking, Tuco handling the stuff with his knife and dropping it on the table would be enough to ignite it."

Still, the point is how the show treats hard science as a way to solve problems. Walter White is something of a superhero due to his education in practical chemistry, and that's a rare thing in television.

So what happened?

The show continues to be an amazing piece of dramatic storytelling, and I watch each week to see what happens next. Last Sunday's season finale was one of the most jaw-dropping hours of television I've seen in years. What I miss is the science, and the scenes where White goes into detail about how he's going to get out of a jam using his scientific background. Now the science is all background, with the ricin being used more as a continual ticking time bomb and the repetition of bodies being dissolved in plastic barrels. We even begin to see White's training fail him, as he has trouble creating a remote trigger for a car bomb that works with any precision.

There is also a satisfying scene in the latest season where Pinkman proves he has been paying attention to the demands of real chemistry by dressing down the gangsters who have put together an inferior lab. Still, there is nothing that compares to the blissful geekery of the show's first season.

This is somewhat disappointing, especially after going back and seeing how much science influenced the early seasons of the show. I'm still going to watch the show, but I miss the days of Walter White the geek. When someone calls himself "Heisenberg" as a way to stay anonymous in his life of crime, it's a shame all the science now happens off camera.
