7 Housemates, New Laundry Rules

I’m feeling rather accomplished and proud of a new document and system I drafted tonight after an impromptu 15 minute house meeting:

House Rules for Laundry

I don’t know why, but I LOVE organizing processes, especially around laundry. And with 7 housemates, we have a strong need to keep the laundry area working stress-free.

We are putting this into effect starting this week. Wish us luck! $10 penalties tend to work well for motivating people in our house :)

Here’s the permanent marker boxes I drew on the dryer, and magnetic name tags to tell whose laundry is where. We are getting organized!

Stop the Dopamine, Live the Life you Want

So this is yet another hypothesis. I realized this tonight after a long day of hair picking/pulling and getting fed up with it. I was thinking of a way to hypnotize myself:

The key to stopping any addictive behavior is to interrupt and repattern the reward circuits in the brain.

When you do something that gives you pleasure, you begin to form a chemical attachment to that activity in the brain. The more the pleasure/satisfaction occurs, the stronger the attachment. Research dopamine.

So, in a moment you are not caught up in an obsessive/addictive behavior, you can actively work on shutting off your dopamine pump toward the undesirable activity.

Imagine this activity your mind loves to do. Now imagine something horrible happening because of it. Become repulsed. Repeat this 10 times.

I found that this was actually a relaxing activity! My forehead and jaw softened as I made the negative association and my breathing deepened. It is as if I snapped myself out of a begging dog posture toward the pleasure of the activity.

For every time you slip up and allow yourself pleasure from the offensive activity, create an equal number of unpleasurable experiences with your imagination. For example, every single cigarette drag, or every nibble at a nail.

I’m excited to try this out. Let me know if you try too!

How Long ‘Til I’m Sick of my Songs?

I remember hearing one time that if you listen to a song over and over, you will eventually reach a threshold where you are “sick” of that song. Either you won’t hear it/register it while it is playing, or you will get annoyed and want to skip it. The number I remember being told was 42 or 46 times (don’t recall exactly).

I have about 300 songs on my BlackBerry right now, which I use when I go out jogging with my housemate’s pit bull. I also use it occasionally on the bus or BART when I want to listen to music, but I’m ignoring that for simplicity.

So I was wondering how long it will take until I get sick of all the songs I have on my BlackBerry. I don’t want to leave the house one day to find that I have to skip over every song on my BlackBerry.

So my calculation went like this:

300 songs

probably have listened to them at least 20 times already, assume 20 more good listens

each song probably averages about 3.5 minutes

So that means, I have about (300*20*3.5/60) = 350 hours of listening left before I am sick of every song, or just about a year of jogging with the dog. Seeing as I started this last September, I am approaching the threshold!

Time to reload/buy more songs.

Ahh, SCIENCE!!

More Theory of Mind Musings, and Why You Suck at Math

If you have not heard of Theory of Mind, it’s quite remarkable: http://en.wikipedia.org/wiki/Theory_of_mind

Basically, as humans, we all have minds, or assume others have minds (!), and we have to interpret what someone was thinking or meaning based off their words and actions. This is a VERY complex data operation, which is probably why you don’t see any computers able to do it yet.

Well, some people are able to interpret or correctly guess what others mean and think much better than others. I happen to be pretty decent at it. I have this validation over 31 years of figuring out what people mean and being pretty close to guessing why things happen most of the time.

I think this is a highly right brain-oriented activity.

I know some people with genius IQ’s who have a LOT of trouble doing this. Their brains are simply not wired to process complex inputs for a correct output. This is not to say they don’t take in inputs – they certainly do, and probably at a rate much faster and higher than normal people do, the problem is they don’t know what to do with all the data once it is swimming around in their minds. They become very LOGIC-oriented as a coping mechanism, reducing the myriad data into discrete, easily-solvable functions, which many times yield simple but incorrect conclusions.

For example, I asked my housemate John, a security guard, whether he sucks at math. His answer is that he is able to take a very large problem and break it down easily, but has trouble with very simple algebra when you start with a short, easily solvable problem. He is also VERY adept at his job, which requires him to figure out what people want and why, even if they are not speaking English.

I know someone VERY intelligent, who relies heavily on people asking him questions, rather than letting him interpret what they are saying and comment back. This is a way of getting around the complexity of the data inputs.

The left brain is more adept at spatial awareness, and processing language and data like mathematics, but lacks complex interpretation skills. That’s what the right brain is for. No, I’m not a brain scientist nor can I point to any specific study that verifies what I am saying, so use your brain to figure out if it makes sense to you or not ;-)

Optimal Daily Walking Length

I had a perfectly lovely date with a Turkish/Italian man last night, who informed me of an awesome dog breed in Turkey called the Kangal (http://en.wikipedia.org/wiki/Kangal_Dog). He mentioned that this huge dog needs something like 7 miles per day of roaming to keep fit and happy, so best to keep them in the countryside where they can go out freely.

This got me thinking whether humans have a similar number for how much walking to do per day. I say walking and not just exercise because I imagine our ancient ancestors spent most of their time walking and not deadlifting, etc. I am wondering how close this 10,000 steps per day fad comes to our optimal walking need. At an average stride length for a man of 2.5 feet, 10,000 steps covers 25,000 feet, or just under 5 miles. This seems really reasonable, especially considering that walking (at 150 lbs) burns about 100 cal/mile, this is a caloric burn of about 500/day. Over a week this equates to 3500 calories burned, saving you roughly a pound of bodyweight from being put on each week.

I think walking also stimulates nerve endings in the feet, acupressure-style, which can stimulate healing processes in other parts the body. Walking without a heavy pack on also helps build core strength and posture support, and good posture can alleviate everything from sinus drip to migraine headaches and back pain.

I mention all this because I used to hate walking. I considered it an inefficient waste of time, and boring. I walked 12 miles on Sunday (with a dog, less boring!), much longer than I’ve walked in a long while, and my body feels so good! I’ve walked/hiked more in the past eight months than I probably have my whole life, and I am in the best shape of my life. Coincidence? I think not.

My guess is I probably do 3-5 miles when I go out, some of that jogging/sprinting. So the numbers are lining up pretty well. Imagine if everyone did this, we’d meet more of our neighbors and all be better looking and more healthy!

365 Challenge

Okay, I’ve seen more than one blog now doing a 365 challenge – Hana/Mike are writing something they are grateful for every day for a year, and I saw Mel was doing a photo a day for a year, so, inspired by them and the Pulitzer prize-winning poet W.S. Merwin, my goal is to write a poem a day for 365 days. As my roommate (who is also a writer) said, even if you write 30 poems, odds are 1 or 2 might be worth reading. Let’s hope so….enjoy!

Campfire Chemistry

11/22/12 Update Note:

This article was thrown up in 2007 after a quick Google research project and it appears that the campfire temperature figure of 2000K was pretty off! The source was a high school teacher’s website as you can see below. Well, that was what was available at the time. There are several other Google listed results now for campfire temperature that seem to put the figure much lower. The campfire clearly didn’t melt the copper and therefore gaseous reactions on the copper side are unlikely, so what explains the color?

It turns out that Chlorine gas (released when burning rubber) reacts with Copper to form Copper Chloride, which is a brownish-yellow solid. Upon reaction with water, Copper Chloride forms, which creates blue and green-colored liquids/crystals.

“Copper(II) chloride is also used in pyrotechnics as a blue/green coloring agent. In a flame test, copper chlorides, like all copper compounds, emit green-blue.” Wikipedia http://en.wikipedia.org/wiki/Copper(II)_chloride

So there you have it – some combination of copper and copper chlorides likely are putting on the show.

______________

So I learned a new campfire trick this weekend that has awakened the dormant chemical engineer in me. I am determined to get to the bottom of this one so my research is below. The trick is that if you buy a tube of copper and insert it into a garden hose (or any other kind of rubber hose, so I was told), and toss it into the campfire, it will create a dazzling light show of greens and blues in the campfire. I believe my hosts inserted a black rubber hose into a copper tube sealed on one side…same effect.

Below is an example of some of the colors.
Copper and Rubber Fire IMG_0125

I was immediately curious about which specific chemicals were involved, and naturally, what heath concerns there were to be had.

All I was able to observe was that there was gas produced by a reaction (the colors did not stem right from the copper tube, they were spread over the whole fire), and you don’t get the normal “burning rubber” smell when it burns in this way. Some people will also bore holes into the copper pipe which supposedly helps the process along.

Here’s my research so far:
Colors: Green & Blue Flames
Campfire Temperature: Up to 3140 degrees Farenheit, hot enough to melt copper and cause many gaseous reactions
Main chemicals involved in producing color: Copper with Chlorine produces blue flames, Copper itself will give off green light when very hot
Health Concerns: Burning anything that contains chlorine/chlorinated plastic will create poisonous gases that will lay the foundation for cancer in your body. Burning rubber/plastic = BAD. Don’t do it every weekend.

Rubber Hose Composition:
“The garden hose material that you seek is to make this colored flame work well is poly vinyl chloride (PVC). When combined with the copper it will produce very lovely flames. When you burn this material it releases several gases. One of those gases being phosgene gas. Perhaps you have heard of this gas. It was quite popular during World War I where it was used as a chemical weapon. I will take my campfires without any nerve gas please.”
http://campingearth.com/blog/2007/03/17/turn-a-boring-campfire-into-a-colorful-light-show/

“The majority of garden hoses are made of one of four types of materials: rubber, polyurethane, vinyl, or recycled rubber. Vinyl hoses are probably the least expensive hoses but they have the shortest life span. Rubber and reinforced rubber hoses are slightly more expensive and also more flexible, hence they will most likely outlast a cheap vinyl hose. A hose with an added layer of outer cord reinforcement (made with nylon or rubber) will best resist abrasion and wear. Hardier, reinforced hoses can withstand weather changes and punctures.”

Rubber Research:
“Indeed, burning tires spew deadly chemicals into the air, including hydrocarbons, dioxins, hydrogen chloride, arsenic, nickel, zinc and chromium.”
http://findarticles.com/p/articles/mi_qn4191/is_20000812/ai_n9973511

“It may come as a surprise to some to learn that most garden hoses leach lead and are unsafe for drinking. Warning labels accompany these hoses in many cases, but not all. A lead-free garden hose will clearly be marked as safe for drinking. These hoses are often sold as marine or recreational vehicle (RV) hoses. While there can be minute amounts of lead found even in tap water, hoses made with polyvinyl chloride (PVC) or brass fittings can leach unsafe levels of lead into the water. Lead is used in the manufacturing process of brass fittings to make the brass malleable in order to shape it, and is also used as a stabilizer in PVC. According to a May 2003 article from Consumer Reports, the Environmental Protection Agency (EPA) deemed safe levels of lead to be less than 15 parts per billion. Consumer Reports tested 16 of the most popular hoses sold nationwide, finding that many leached up to 100 times that amount at the initial flush of standing water. http://www.wisegeek.com/what-is-a-lead-free-garden-hose.htm

Campfire Temperature: “A camp fire is ~ 2,000K” (That’s about 3140 degrees Farenheit) http://www.newton.dep.anl.gov/askasci/gen06/gen06272.htm

Plastics Research:
Burning plastics is also very very bad for you. Backyard trash burning is thought to be one of the biggest sources of dioxin poisoning.
“Some types of plastic contain elements besides the standard carbon,hydrogen, and oxygen. Nylons contain nitrogen, and polyvinyl chloridecontains, of course, chlorine.”
http://www.newton.dep.anl.gov/askasci/chem00/chem00031.htm

Copper Research:
From the Cupric Chloride MSDS:
“copper fume…can cause symptoms similar to the common cold, including chills and stuffiness of the head.”
http://www.jtbaker.com/msds/englishhtml/C5863.htm

“Copper (I) chloride salts imparts a blue colour to flames. The picture above shows the colour arising from adding cuprous chloride (CuCl) to a burning mixture of potassium chlorate and sucrose. This flame is relatively cool. Hotter flames burn green bacause of emission from copper atoms (only to be demonstrated by a professionally qualified chemist following a legally satisfactory hazard asessment).”
http://www.webelements.com/copper/

“When you heat copper ions, the energy “excites” electrons and pushes them into higher energy levels. Being in this excited state is not particularly stable, so the electron rapidly returns to the ground state and emits a photon (a particle of light) to release the energy it gained by being excited. These photons are the green light you see from excited copper atoms returning to the ground state.”
