Title text: I mean, what's more likely -- that I have uncovered fundamental flaws in this field that no one in it has ever thought about, or that I need to read a little more? Hint: it's the one that involves less work.
The comic contrasts brilliant revolutionary scientific thought with the simplistic arrogance of assuming one understands the current scientific theory enough to correct it. The character with the goatee has a degree in philosophy, and perhaps has certain ideas of his own about how the world should fundamentally be described by physics. He has studied Einstein's theory of special relativity for less than an hour and thinks it is wrong, and that he has a better theory. When confronted about this, he considers the objection as based in dogma, and remains so confident that he wants to email the "president of physics". His ignorance of the field is emphasized by thinking that the entire field of physics has a president - although certain important organizations such as the American Physical Society do have presidents.
Cueball concedes that it is possible for such a revolutionary idea to come from a relative outsider. One example is Albert Einstein's own formulation of special relativity, which came while he was working at a patent office in Switzerland, although he did already have a Ph.D in physics. A thought experiment considers some hypothesis, theory, or principle for the purpose of thinking through its consequences.
The "racecar on a train" idea alludes to thought experiments involving frames of reference, which are important in relativity.
The title text compares two possible scenarios:
- That I have uncovered fundamental flaws in this field that no one in it has ever thought about (implying that decades of work by numerous physicists is fundamentally incorrect)
- That I need to read a little more
Usually, when someone with little understanding of the subject (such as the philosopher) thinks that they have found a flaw, it takes only a little bit more reading to discover that the flaw is in fact completely explained already. The 'Hint: its the one which involves less work', points out that its far less work to read through the existing knowledge on the subject than re-derive it from first principles.
As an example, lets say a high school student happens to do sqrt(5-6). His calculator tells him 'Error', and he thinks he has uncovered a sum which has no answer. In fact, with a little more reading, he would discover that mathematicians have a whole area devoted to this type of maths, namely imaginary numbers.
- Cueball: Yes, science is an open process in which a good idea can come from anybody.
- Cueball: Yes, widely-believed theories are on occasion overturned by simple thought experiments.
- Cueball: And yes, your philosophy degree equips you to ask interesting questions sometimes.
- [Cueball is talking to a philosopher with a goatee, who is sitting at a computer.]
- Cueball: But you did not just overturn special relativity, a subject you learned about an hour ago, with your "racecar on a train" idea.
- Philosopher: You just don't like that I'm turning a rational eye to your dogma. Hey, what's the email for the president of physics?
