Supersense

Rating: ★★★★☆

Supernatural beliefs are often associated with religions or superstitious. Does it mean that an atheist or a scientifically-trained highly-rational person is immune from super natural thinking?

We try to avoid touching things that criminals have touched or living in the room that people have died, but eager to shake hands with celebrities. We invite FengShui master exam the house before buying in. We enjoy ghost stories and often get frightened by them. We believe certain naturally-produced weird-looking food has healing power although there is not scientific proof of it. We treasure family album and it is the first thing that most people would save if their house got on fire. Every culture has certain colors, numbers and activities that are considered fortunate or unfortunate. In fact, it is often easier to accept the supernatural beliefs than to reject them.

You may shrug them off by thinking that we only do these things to comply with social norms. However, precisely the reason that they become social norms, instead of just individual beliefs, is worth more studies. The studies are often conducted on children, from new-born baby to teenagers, because they have relatively short time to be influenced by the cultures they lived in. It turns out that the supernatural beliefs can often be rooted to our human nature of recognizing the world around us. We have a tendency to look for human’s image from the cloud, the smoke and the foliage of the forest. This is not surprising because the studies show that babies are very sensitive to human faces. We also tend to classify objects and try to group them into some familiar things. This is an important way to expand our knowledge into unknown world. The same behavior can also be seen in children in early ages. In fact, if something is too different and cannot be organized, we often ignore them or even disgust them.

Throughout the book, the author shows us supernatural beliefs are unavoidable no matter how rational or educated we become; at the end, the author tries to conclude that they are maybe a good thing. We learnt them through millions years of evolution and they are programmed in our brain. They are the surviving skills to bring us here and they will continue evolving with us and the environment.

This is a fun book to read with good balance of intriguing anecdotes and scientific evidence. I can see myself through the book as I share many supernatural thoughts that I wasn’t aware of, and I find satisfactory explanation that make me “Eureka!”. It is the beauty of science.

A Snapshot of Internet from Google Analytics

Sep 19 2009 Published by admin under Blog

Google Analytics not only maintains how many visitors your website has and where they are from, it also has detailed breakdown of how they get to your site. From these statistics, you can more or less sense the current status of Internet. It is interesting to study them and compare them from time to time to see the transition of the computer industry.

The following screenshots are from Google Analytics of my blog site. My site has only about 900 visitors so far, but I think we can see some trends already. The noises made by my own visits should be mostly eliminated, because I can configure WordPressGoogle Analytics plugin to not to send statistics to Google for logged in users.

Operation Systems: Windows dominate; MAC has 13% market share.

Move to BlueHost Web Hosting Service

Sep 14 2009 Published by admin under Blog

I have been using my home PC to host my website and gallery for almost 10 years. I had a good experience moving my gallery to Zenfolio and SmugMug (updated review here), access is faster, uptime is better and storage is really cheap these days, so I felt it’s a good idea to host my website on a professional hosting service as well.

I compared features and fees of a couple of hosting service and talked with two customer service agents. Because most pages of my website are driven by MySQL and PHP, these are the must-have features. Eventually, BlueHost stands out among others. It is the first recommendation in WordPress website and its online reviews are mostly positive. Although most services I evaluated provide similar features, bluehost’s website just looks more professional. The new user has 30-day money back guarantee, so I decided to go with it.

Banff and Jasper – Day 3 (2009/8/9)

Sep 09 2009 Published by admin under Blog

Today’s plan was to visit Bow Lake and Peyto Lake. As they are at least 1.5-hour drive from where we stayed, I couldn’t make the early morning trip, so we decided to leave after noon. In the morning, my wife went out for shopping and I could take some random shots in nearby places. I took a short loop of highway 1 – 93 – highway 1A. It was quite disappointing. The day was haze. The lighting was even worse than the noon time yesterday.

Elks in Vermilion Lake It was about 11AM when I finished the loop. As I almost exited highway 1 to enter Banff town, I turned my head to the right to see what the Vermilion Lakes looked like from the highway. I saw something standing in the middle of the water. I looked again to confirm those were either moose or elks. Quickly exited the highway, I drove myself to the lake side. Some people were there pointing to the animals, and I saw some rafts could literally touch them. Finally I could put my 2x teleconverter to use now. However, even with 2x teleconverter and 200mm lens, those animals were still too far to see from the camera. I thought maybe I could get closer to them by land, so I parked my car at a nearby trail head, put on the 70-200 mm lens and almost run to the trail. Unfortunately, the trail was separated from the lake by a river. At one point, I almost wanted to walk over a falling tree to get to the other side, but I didn’t have the guts. It’s not a creek, it is a river. I met my wife at the hotel and took her to see them over the Vermilion Lakes. I thought I was going to miss the best chance for the photos of the wildlife. I didn’t know I could watch them so close later today.

Peyto Lake It took us indeed one and half hours to get to Bow Lake. The lake was big. Similar to Lake Louise, the color was turquoise. The beauty of the Bow Lake is you can view the glacier hanging over the lake at the water front. The problem was the Sun was against us and the overcast sky kept me from a perfect photo. Peyto is only 20 minutes to the north. It started drizzling when we parked our car. The greens became denser but I worried the lake would be too dark. The trail to the lake cannot be called steep because it is really very short. The lake sat far below the overlook, again, in turquoise color. It is fed by the Peyto Glacier and the surrounding mountains provided perfect backdrop to the perfect-shaped lake. The only thing not perfect was the weather. We waited more than half an hour, then my patience paid off. The Sun came out so I could take some pictures.

Rainbow As we drove back on highway 1, it rained quite hard but soon cleared up. A beautiful rainbow appeared over the Bow river against the mountain peaks. This was an easy day compared with yesterday. We thought that’s it for the day, but as we took a shortcut to the hotel, I heard my wife shouted, “What is that?” It was an female elk, by herself, walking around the railway station.

Elks in Banff Town We stopped the car. The elk apparently was aware that we were following her, so she nimbly crossed the rail tracks and stood far from us near a grove. We decided to check her back later. I dropped my wife at hotel, got the lenses prepared and quickly came back to the station. The elk is gone, but somehow I felt I saw something in the wood, so I crossed the rail tracks and walked into the grove. The elk is there, by herself again, having her dinner. She was an adult elk, higher than me and must weight twice as much as I do. I tried to sneak around the trees so she wouldn’t run away, but it seemed the elk was not alerted at all. Sometimes she did see me eyes to eyes, but she just turned back having more leaves. The closest I got was less than 20 feet from her. With my 70~200mm lens, I could take the close-up shots quiet easily. I was the only one in the wood with the elk. After about 10 minutes, she had enough dinner and I couldn’t stand the mosquitoes any more either, so she run out of the woods and disappeared in another grove. I pondered if I should check the herd in the lake area, but there was no easy way to access unless I took the raft. Then, the elk appeared again around the railway station, this time, with a young elk. I am glad she wasn’t with her child in the grove. I am not sure if she would be more vigilant or even attacked me if she had her baby on her side.

Elks in Banff Town On my way back to the hotel, I saw many people standing around Banff’s fire department, then I noticed a herd of elks having their dinner on the fire department’s grass field. There was a male elk, clearly the head of the group. I think that must be the same herd I saw in the lake earlier today. I could take pictures of them just across the road, but the background were people and buildings.

I felt very rewarded for seeing something wilder today, although I could see the elks had already got use to people watching them closely.
