This is a first post in a blog about physics.
Well, not just physics. Also other areas of science in general. Math will also be pretty popular. What is this all about? I’m not sure yet. I guess I’ll figure it out as time goes by.
What I can answer now is what led me to this. I will shamelessly blame other people I know, by telling anecdotes. Not too long ago, when I was in Stony Brook, Jacques Distler said to me:
JD- We have to get you blogging, heck if you want to, just send me your TeX files and I will make sure that they get posted.
DB-I’ll think about it.
That was my answer. Then I got some e-mail from some friends suggesting that we start a group blog, but there is the issue as to how much time a blog takes away from a persons life, so their commitment was along the lines of “I’m in if you’re in” sort of thing. In any case, I decided that it was not a crazy idea and that I would give it a go. So I’m hoping that as time moves forward, more friends will join me and then everything will be easier for me. Moreover, when I talked to some people hoping that they would dissuade me from it, they said “cool” instead.
Next came the subject of the blog. Yes physics: after all, I am a physicist and that is what I wanted to Blog about. That was not the issue. More like what kind of physics and for what reason was I really blogging?
You can insert a soul searching diatribe here. Pick your favorite. I don’t care. What I do know is that I’ve had illusions of being a writer -not just of technical papers- so this is a place where I can experiment.
The other thing that has happened is that I’ve had many conversations in airplanes where I have realized that people in general do not have a clue as to what physics is all about and why it is so important for humanity. The conversations go like this:
Passenger- Nice to meet you.
DB- Nice to meet you too.
Passenger-So what do you do?
DB-I’m a physicist.
And then the person who is staring at me, if he does not decide that he is too scared, gives me one of the following lines:
- I see. So what is that good for?
- So you’re good at sports?
- That was my worst subject in high school.
- I never understood physics
- You must be a genius.
- I wanted to be a physicist, but I became an engineer instead.
Well, that last one I have only heard once. But there are other variations. I also teach physics courses in the University and have realized that for many students “physics” is what happens in the classroom and it has no bearing on real life. So I thought it might be a good idea to correct those misconceptions and set the record straight. Physics happens everywhere, all the time. It does not stop from happening just because people want to be ignorant about it.
The last thing to think about was style. Heck, I want this to be a friendly site, where technical words do appear but they don’t turn off people away from physics. I decided that it would be nice if I could have a casual style. So that it reads like a conversation, somewhat humorous even though I’m not a great jokester. Hopefully in the end people would (will?) learn something fun and -*ahem*- important.
There is a precedent for this. Galileo had some nice things to say about physics, and he said it in a mocking way. There were three characters, Salviati,Sagredo and Simplicio. One was Galileo, the other was the orthodoxy, and the third one was a mediator. And Galileo would win in the end. It would be pretty pathetic otherwise. But the case was pretty convincing.
So these are the reasons why. Now, I will have to hide and come up with something brilliant by tomorrow.
By the way, as an afterthought, I also thought this would be a good place to communicate with colleagues about general stuff, like conferences and such, and maybe about some neat trick that I would not be able to publish elsewhere. Even perhaps about some more exotic aspects of physics.

“Hehehe.” he says, rubbing his hands together, “Everything is unfolding, according to plan.”
Welcome, and Congratulations!
Ooooohhhhh…. this is going to be so good!

Hi David! I will try to drop by with reasonable frequency. (Ah, frequency! That would be a physics term, I suppose?)
Welcome to the blogsphere! As an (ex)physicist I’m looking forward to your posts!
Hi there, and welcome! I came here via Mark at Cosmic Variance.
I’ve also got that list of responses a number of times – even number 6 – but I can honestly say I’ve _never_ heard number 2 before. Huh. Mostly I’m met with trepidation.
“Physics happens everywhere, all the time. It does not stop from happening just because people want to be ignorant about it.”
THAT has to be one of the best statements I’ve read regarding “everyday physics” and people’s perceptions.
Looking forward to reading your blog
Nice title. Are you LaTex enabled?
Let’s see:

“I wanted to be a physicist, but I became an engineer instead.”, you must have been on a plane with me. The only time I have really regretted not becoming a physicist was the day I got a tour of SLAC. I guess I just really liked making things.
Anyway, I look forward to your posts.
Good luck
I like this:
I wanted to be a physicist, but I became an engineer instead.
The reason for liking it so much is actually quite simple. I’m only 18 years old, I know a lot of people my age don’t know exactly what they want to do yet, but most do have a couple fields of interest. As you might be able to guess, mine are Engineering, Physics, and actually Astrophysics.
The latter of the 3, Physics and Astrophysics, have always interested me by exploring the unknown and figuring out exactly what makes the world work. Engineering has caught my eye as the field where it’s all about physical application, actually seeing the science come to fruitation (which apparently ISN’T a real word).
All this rambling is getting at something, and I really hope you can get back to me. As a physicist who probably knows some engineers in the field, could you offer me some advice about what happens in each field? Separating the harsh reality to the dreamy Hollywood jobs we all know and love.
My email address is submitted with this comment, so feel free to answer me anytime. Also, I won’t hold anything against you for not answering.
Thanks,

(I know I didn’t really include much about my personality, but I didn’t want to put all my eggs in one basket.)
Man, I get 1, 3, and 5 (or minor variations thereof) ALL the time. Mostly 3 and 5, sadly.
I often got this variant of 3: “I took math in high school”. A few decades ago, by chance, I discovered that I always get a smile when say “I am an astronomer”, so that’s what I say now.
I’m usually asked about horoscopes. Depending on who I’m talking to, or what she looks like, I do anything from comment wisely on their birth sign to talk about an experiment I did disproving an astrologer’s ability to predict personalities from the exact birthdates.
Except now I sometimes say “I’m an astronomer that got old”.
So it goes.
