To Criticise Or Not To Criticise

By
There's a strain of thought that says because so and so did such and such then so and so's opinion on X (provided that the opinion agrees with your opinion) can not be questioned or challenged. Take for example serving in the military. Folk are crying foul because Rep John Murtha, a former Marine now serving in the US Congress, is being criticised for calling for US withdrawal from Iraq.

Serving in the military does not make anyone infallible nor omniscient (neither does losing an adult child in Iraq who volunteered to be there by the way). For those who would use their service in the military to shield themselves from criticism, if your fellow Americans are not free to challenge your ideas, dissect them and analyse them, and say you are wrong then what exactly did you serve to protect? What did you fight for and your compatriots die for if the ideas of all Americans do not stand on the same footing and are subject to the same scrutiny?

What's in a flower?

By
Specifically hydrangea flowers. In this post I pointed out that anthocyanin (a family of plant pigments) appears blue at high pH, red at low pH and is responsible for the wide variety of colours in hydrangea flowers. Ilona pointed out that , "in hydrangeas you lower the ph for blue flowers (more acid) and raise it for pink (more alkaline)." I did a bit of checking and found that this is the case . At lower soil pH hydrangea flowers do appear blue and at higher soil pH they appear red. But soil pH is not the only thing that affects the colour of hydrangea flowers. It appears that pH inside the plant cell has an affect as well: Sepal Color Variation of Hydrangea macrophylla and Vacuolar pH Measured with a Proton-Selective Microelectrode Anthocyanin changes its color depending on pH (Goto 1987, Brouillard 1988, Goto and Kondo 1991). In strong acidic conditions it shows red, in neutral, purple and in alkaline, blue. But generally the vacuolar pH of plant cells is weakly aci

Treating autism as traumatic brain injury

By
I've been doing research into autism, dyspraxia, how the normal brain works, and how an autistic/dyspraxic brain works (or doesn't work). Traumatic injury to different parts of the brain can cause the same problems suffered by autistic and dyspraxic children. Compare this list of the functions of different parts of the brain and the problems caused by injuries to those areas with these descriptions of dyspraxia and autism. What is Developmental Dyspraxia? Developmental dyspraxia is a disorder characterized by an impairment in the ability to plan and carry out sensory and motor tasks. Generally, individuals with the disorder appear "out of sync" with their environment. Symptoms vary and may include poor balance and coordination, clumsiness, vision problems, perception difficulties, emotional and behavioral problems, difficulty with reading, writing, and speaking, poor social skills, poor posture, and poor short-term memory. Although individuals with the disorder may b

Battlestar Galactica needs more colour?

By
Here are the letters I mentioned in the previous post. The one that started it (I'm guessing these letters were written after the show's first airing at the end of 2003): Galactica Needs More Diversity The problem I had with Battlestar Galactica was there were no major and very few minor African American characters. There were no Black men in the show at all or if they were, they had virtually no screentime. In the original series, Boomer and Tigh were both played by African American actors. In this rendition of Battlestar, those characters were played by Asian and White actors. In the Caprica city, there no African American extras. On the Galactica's bridge, there was only one African American actress. Another Black actress could be found playing a religious official that swore in the new President of the colonies. This was very troubling to me. Do you not want African Americans to watch your show? Do you want to project the idea that African Americans are not part of the
