Lobby of the Mojave desert inn
Btw, We did drive past the airforce base earlier this morning. We did have our hopeless fantasies of catching a glimpse of the shuttle from the highway, but as rationally expected, saw nothing more than a vast desert.
Oh well!!

Astro-vacation - day 1
Initially, we thought we could do the 12 hour drive from San Francisco to Flagstaff in a single day. Now I know that would have been crazy. We looked up an appropriate mid-point and chose Mojave, CA to spend the night.
As we checked into the Desert Inn in Mojave, we saw a bunch of photographs of the space shuttle in the very modest looking motel office. It suddenly struck us that we must be pretty close to the NASA facility in the California desert. The inn-keeper later confirmed that we were just a couple of miles away from Edwards Airforce base where the space shuttle landed just yesterday!!! What a great and surprise start to this Astro-vacation!

An awesome idea for Earth Day !!

Malvika got a gift from her company as part of Earth Day. It is a shopping bag that easily packs into a small size and can be fitted to your key chain, your belt or back pack. This solves a major problem I have been having with avoiding plastic bags i.e. remembering to take my own shopping bag. Great example of what you can achieve when you apply your mind to a certain problem.
You can check out the bags at http://www.chicobags.com

Bandipur Jungle song - now with a video
Now I have a video to go along with it. All the video clips are from the trip we made to Bandipur. Most of the stills at the end are from awesome paintings in the rooms at Jungle Lodges and Resorts.
I made the video with Cinerella. I used the version that came with a dynebolic distribution of linux. It has a huge learning curve, but once you get the hang of it, it is quite powerful. This is my first attempt at doing a full video with Cinerella. In hindsight, I do wish I had a tripod or a much more steady hand with the camcorder.

What will you be doing on September 9th, 2040 at 7:00 PM?
Click on the picture to see a larger resolution version and to be able to read the labels.

I learnt about the solar system in school like everyone else, but I never "really" got a feel for it. I never connected that knowledge to what I would see when I would look up at the night sky. I vaguely remember visitng a planetarium (Nehru Planetarium in Mumbai), but do not remember any astronomical insights I gained from the visit. My wife, Malvika, is an astronomy enthusiast. She volunteers during the summer programs at the Lick Observatory. Thanks to her, I have seen Jupiter and other sky objects through a couple of large telescopes. (a 36-inch refractor and a 40-inch reflector) That experience definitely awed me, but more for the awesomeness of the telescopes than that of the sky.
Until recently, I have never been able to look up at the sky and "feel" my place in the solar system and the galaxy.
What finally gave me that feel is this interactive sky chart at Sky and Telescope. The chart allows you to see the sky as it looks from any place on earth at any given time. That alone would not have done much for me. What was cool is that I figured out a way to quickly change the time and see a kind of a time-lapse. See notes at the end of the article about how to do this. The most meaningful time-lapse I was able to see was the state of the sky at the same time every night. i.e. Imagine making a movie with each frame being the state of the sky at the same time every night and then extending this over multiple years. The resulting movie gave me more insight into the sky and the planets than anything I have encountered so far. Here is a youtube upload of the screen capture. It does not do justice in terms of resolution or frame rate, so you should definitely try this out for yourself.
Insights I gained:
- If you look at the sky each day at the same time, the view shifts ever so slowly. This is a direct result of the earth moving around the sun and thus pointing to a slightly different direction in relation to the sun every day. It completes this cycle once every year. Hence, based on which constellation you are seeing at a particular point in the sky at a particular time, you could tell with precision which day of the year it is.
- I had always heard that the planets move through the constellations. Think about it and it is obvious that as the planets move around the sun, they will appear to move in the cosmic backdrop of stars. However, I never had a feel for exactly how that "looked" in the sky. You see Jupiter and Saturn move more slowly against this backdrop than Mars, Venus and Mercury. (hinting at their relative distances and orbit times).
- You could deduce that Mercury and Venus were in an inner orbit because of the fact that they never cross the sky from east to west in this time lapse like Mars, Jupiter and Saturn do.
- Jupiter and Saturn seem to come really close to each other from earth's perspective every 20 years. The next time this will happen for us is in 2020. Being able to see all 5 planets at the same time in relative close proximity in the sky is pretty rare and the moment in 2040 that is the title of this post is very rare indeed.
- The plane of the planetary orbits is not the same plane as the galaxy. You can see this in the movie by seeing the planets cut across the milky way. Had these planes been more aligned, we would have seen the planets move "through" the milky way. For some reason, my internal mental image had always aligned these planes.
This chart turned out to be an awesome tool to let me really "feel" my position in the solar system and the galaxy. I wish this was available to me when I was first learning about the solar system.
How to create this timelapse using the interactive chart:
There are small controls on the left side which allow you to change any component of the time (i.e. year, month, date, hours, minutes, seconds, etc.). There is a "+" and a "-" button which increments any of those selected components. If you press the "+" button and just move your mouse around, the value keeps incrementing.

The "Saahas" to eliminate plastic bag use
We had Ms Hema Ramana from Saahas visit our apartment complex today to talk about our waste management.
A few people attended the session. I have uploaded an edited version of the session that I videotaped. Its about 10 minutes and captures the main points that were communicated.
Saahas works in the solid waste management space. While there are a lot of things that can be done, for now Saahas is asking us to actively participate in their Less Plastic for me initiative.
We are being asked to eliminate our use of plastic bags. If you wonder why plastic bags are bad, a quick look at this website will tell you why.
I did take a look today and it is a very short website (wont take more than 10 minutes, but communicates the problem very clearly). There is also an accompanying blog if you want more information and news about this issue.
What can we all do immediately:
- Start carrying our own bags to grocery stores and other shops. Refuse plastic bags at shops wherever possible. Hema has left a few bags with Gowda (our apartment manager). Small ones for Rs. 30 each and large ones for Rs. 150 each.
- Stop giving our garbage in plastic bags. Use two dustbins. Empty one and immediately wash it and dry it. Use the other one for the day while the first one dries up.
These arent easy things and will require a change in our habits. This evening I was out and while returning I decided to stop and get some groceries. Then I realized, I didnt have any of my own bags and would be forced to accept plastic bags at the store.
I could have driven back home, carried my own shopping bag and gone back to the store. But I was short on time and ended up making the compromise. I felt guilty and the least I could do was combine all my shopping in a single plastic bag.
What I am going to do now is just keep a couple of cloth bags in the trunk of my car, so I'll always have them handy if I do happen to just stop by at the store. I am sure you all can do the same.
The second item of not using plastic bags to dispose off garbage is even tougher and I am not even sure I want to do it from a hygiene perspective. What do you think? There have to be better alternatives than washing and drying dustbins daily. Hema was talking about some company selling bio-degradable garbage bags, but I do not have information about availability or cost.
What we can do in the medium term in other areas of solid waste management:
- If everyone in the apartment complex agrees, then we can segregate waste right at home. We will just be asked to separate dry and wet waste. Saahas will train our housekeeping staff in the building to collect it separate and keep it separate. They will then further train our housekeeping staff to segregate dry waste further.
Saahas will help us collect dry and wet waste separately and ensure it is properly handled and not mixed up after it is picked up from our apartment. This will need some space in our apartment complex to do the secondary segregation. - If we do have plastic bags and we will inevitably have some even if we reduce our usage, someone in the apartment will need to collect them and drop all the plastic bags in the facility that Saahas has in Jayanagar. (This will need one of us to volunteer)
What we can do in the long term and potentially earn revenue through our waste:
- A compost facility or waste processing machine located within our apartment complex or feed our wet waste into other compost facilities in HSR. (whenever they are setup).

Vote for the term "cloudworker"
Venkatesh Rao, a blogger at ribbonfarm.com who I read regularly, coined the term "cloudworker" and entered it in a contest, run by Plantronics, to update the obsolete term "telecommuter." The term is one of the 10 finalists out of over 500, and I really think it deserves to win, since it captures how remote workers today use cloud-based technology to work anywhere/anytime.
The winner will be selected by popular vote, so please go towww.plantronics.com/telewho and vote for "cloudworker". You can vote once a day between Oct 30 and Nov 7, so it'd be great if you could bookmark the link and remember to vote multiple times.
You might like Venkat's ongoing series of posts on cloudworkers:
