Happy Pi Day (3.14) Domino Spiral

Sat, 14 Apr 2012 16:43:57 GMT

Or Half Tau Day...to mark the day, I've made my biggest spiral yet...and using a formula with Pi, I estimated the total dominos in this spiral to be 10178.75 dominos. I counted the dominos and the estimate was close. 10,059 dominos were actually used.

Can you spot the 2 hidden references to 3.14?

Conrad Wolfram - Making Maths Beautiful

Sat, 25 Feb 2012 23:17:41 GMT

Conrad Wolfram, Mathematician Founder, Wolfram Research Europe. The importance of math to jobs, society and thinking has exploded over the last few decades. Meanwhile, math education has gotten stuck or has even slipped backward. Why has this chasm opened up? It's all about computers: when they do the calculating, people can work on harder questions, try more concepts, and play with a multitude of new ideas. Conrad Wolfram discusses a new project to build a completely new math curriculum with computer-based computation at its heart - alongside a campaign to refocus math education away from historical hand-calculating techniques and toward relevant and conceptually interesting topics. Presented at the Learning Without Frontiers Conference, January 25th 2012, London http://www.learningwithoutfrontiers.com

Gapcast #11 - Reducing Child Mortality

Sat, 25 Feb 2012 21:23:52 GMT

Nearly 10 million children under five die every year. Almost 90% of all child deaths are attributable to just six conditions: neonatal causes, pneumonia, diarrhoea, malaria, measles, and HIV/AIDS. The aim (Millenium Development Goal 4) is to further cut child mortality by two thirds by 2015. How can this be achieved? Which countries make sufficient progress? And with which rate did a country like Norway reduce its child mortality the last 100 years? Watch Gapcast #11 to understand the background and the current status of a Millenium Development Goal.

Poor beats rich in MDG race

Sat, 25 Feb 2012 20:58:55 GMT

Hans Rosling details the progress towards reducing child mortality.

Yes they can!

Sat, 25 Feb 2012 20:56:47 GMT

Yes they can! says Hans Rosling about low and middle income countries that, with economic and health progress, are catching up with high income countries – countries we used to call the western world.

Shanghai, New York, Mumbai

Sat, 25 Feb 2012 20:55:55 GMT

A video from Gapminder with Hans Rosling telling the story of three big nations (China, USA and India). First, see the development of three centers of trade, Shanghai, New York and Mumbai. Secondly, a comparison of the capitals: Beijing, Washington, D.C. and New Delhi. And finally, a note from Professor Rosling on how one can measure the progress of President Obama's intentions to improve the health system.

Cervical Cancer Statistics

Sat, 25 Feb 2012 20:54:47 GMT

Cervical cancer is common cancer among middle-aged women. By better prevention, treatment and health education many countries has seen fantastic progress and saved thousands of women.

Stomach Cancer Statistics

Sat, 25 Feb 2012 20:53:49 GMT

In this video, Hans Rosling shows that stomach cancer is rare in the poorest countries and the rate of this cancer reach a peak in middle income countries. When countries get still richer the frequency falls. This is in sharp contrast to breast and colon cancer that tend to increase in frequency as countries get richer and richer. The rate of stomach cancer has been especially high in Japan and China. In Japan, wide-spread screening programs using the Japanese endoscopy invention have contributed to reduced death rate in this cancer. Having seen the video you can look yourself in Gapminder World where the cancer data from IARC (International Agency for research on Cancer) is displayed as moving bubbles. http://is.gd/CK3n - New cases of stomach cancer per 100 000 men (with size showing the total number of new cases of stomach cancer)

Colon Cancer Statistics

Sat, 25 Feb 2012 20:52:42 GMT

In this video, Hans Rosling shows that cancer in the large intestine, i.e. colon, gets more common when countries get richer. The data is compiled by IARC ( International Agency for research on Cancer) in Lyon, France. It reveals that colon cancer is equally common in men and women, that eat similar diets, in high-income countries. Prevention through promotion of health diet have not yet had any big effect but advanced screening programs and improved treatment have decreased the death rate among colon cancer patients in high-income countries. It is paradoxical that high-income leads to a diet that cause this cancer while at the same time only high-income can support a health service that can cure it. Effective prevention could avoid a lot of suffering and save money for health services. http://is.gd/CJKJ - New cases of colon cancer per 100 000 men (with size showing size of population)

Liver Cancer Statistics

Sat, 25 Feb 2012 20:51:50 GMT

In this video, Hans Rosling uses liver cancer statistics to show how cancer data from IARC ( International Agency for research on Cancer) can be displayed as moving bubbles in Gapminder World. In this visual way, you can easily compare data for the most common cancers and rapidly understand that each of them have different distributions in the world. Liver cancer is mainly caused by chronic infection by the Hepatitis B virus (and also by the Hepatitis C virus). As this infection is most common in China and other parts of East Asia, as well as in Africa South of the Sahara, it is the countries in these regions that bear the main burden of Liver Cancer in the World (independent of if they have low, middle or high income). Comparing gender differences indicate that higher alcohol consumption in men may explain why the rate of liver cancer in men is twice as high as in women. http://is.gd/CJWA - New cases of liver cancer per 100 000 men (with size showing the total number of new cases of liver cancer)

Breast Cancer Statistics

Sat, 25 Feb 2012 20:51:04 GMT

Breast Cancer is the most common form of cancer among women. It is more common in rich countries than in poor and it increase when a country gets richer. But with increased income comes also better chances to save those women that get cancer. New Cancer-data in Gapminder World shows how more and more women in a country like Sweden gets breast cancer every year but also how fewer and fewer dies from that cancer. Today, most people that get breast cancer in Sweden survives. See more at: www.gapminder.org

Prostate Cancer Statistics

Sat, 25 Feb 2012 20:49:56 GMT

In this video, Hans Rosling briefly reviews the risk of getting diagnosed with, and the risk of dying from, prostate cancer in the world. The data is compiled by IARC ( International Agency for research on Cancer) in Lyon, France. The most striking is the high rate of diagnosis per 100 000 men in USA and some countries in West Europe. In contrast, Japan has a very low rate and the most probable explanation is a genetic predisposition in men of European origin. The data is displayed in bubbles for each country and the color of the bubbles refers to the continent where each country is situated.

Lung Cancer Statistics

Sat, 25 Feb 2012 20:48:37 GMT

Lung cancer remains a deadly disease and most cases are caused by cigarette smoking. Using data from IARC ( International Agency for research on Cancer) in Lyon, France, Hans Rosling shows the dramatic differences between men and women, between countries and between different decades in the same country. They are due to variations in tobacco smoking in the world. Most people in low income countries cannot afford many cigarettes, and hence have low risk for lung cancer. Middle income countries have the highest frequency of tobacco smoking, and hence of lung cancer. In most high income countries health education and regulations are having effects, tobacco consumption is reduced and so the risk of lung cancer in men. But unfortunately smoking and lung cancer is still increasing in women in many countries. Iceland is the first country to reach equal smoking frequencies in men and women and now also have the same risk for lung cancer in both sexes. In spite of growing concerns for environmental toxins, tobacco smoking remains the most important avoidable cancer risk in the world.

Human rights & democracy statistics

Sat, 25 Feb 2012 20:47:08 GMT

In this video, made for the Oslo freedom Forum 2009, Hans Rosling talks about the difficulty in measuring progress in Human Rights in the form of comparable numerical statistics. He also shows the surprisingly weak correlation between existing estimates for democracy and socio-economic progress. The reason may be that democracy and human rights measurements are badly done. It may also be that democracy and human rights are dimensions of development that are in themselves difficult to assign numerical values. But it also seems as much improvement in health, economy and education can be achieved with modest degrees of human rights and democracy. Hans Roslings concluding remark is that Human rights and Democracy maybe should be mainly regarded as values in themselves rather than means to achieve something else.

Swine flu alert! News/Death ratio: 8176

Sat, 25 Feb 2012 20:46:16 GMT

During the last 13 days, up to May 6, WHO has confirmed that 25 countries are affected by Swine flu and 31 persons have died from Swine flu. WHO data indicates that about 60 000 persons died from TB during the same period. By a rough comparison with the number of news reports found by Google news search, Hans Rosling calculates a News/Death ratio and issue an alert for a media hype on Swine flu and a neglect of tuberculosis.

NCETM | Price comparison

Sun, 29 Jan 2012 15:58:33 GMT

Overview: The company, EDF, is one of the largest energy suppliers in Europe with 5M customers. In this clip customers want telephone operator Will, to give them a price comparison with their existing company. He uses of a formula where a higher rate is charged on the first 5480kw of energy and the remainder is charged at a lower rate. Once the total has been calculated Will needs to add the VAT percentage. The customer could make a saving of over £50 by changing to EDF. During the call he uses a formula, percentages, decimals, proportions and a calculator.

NCETM | Using solar panels

Sun, 29 Jan 2012 13:54:06 GMT

Overview: Matt Hobby works for the National Centre for Atmospheric Science. His role is to design and develop instrumentation and to build prototypes. One of the devices he deals with is an automatic weather station. These are often installed in remote places around the world and need to be powered by solar energy. Voltaic panels are placed in sunny locations to charge lead-acid batteries which will power the weather station. The energy generated by the solar panel must be greater than the power needed, so the size and angle at which the panel will be mounted (the angle of incidence) must be calculated carefully to match the local conditions. The mathematics he uses involves area, angles, and measuring energy used and supplied.

NCETM | Investing in waste management

Sun, 29 Jan 2012 13:52:18 GMT

Overview: The University of Leeds has 32,000 students and 7,000 staff. Dr Keith Pitcher is Environmental Officer. One of his main responsibilities is to encourage a greener attitude to waste management. Keith has had to balance a £90K investment in recycling equipment and facilities with the rising cost of sending waste to landfill. In 4 years the university has increased the percentage of its 1600 tonnes of waste that is recycled from 16% to 40%. In the same time landfill tax has increased from £12 per ton to £24 and will double again in the next 2 years. Keith expects their investment to be repaid in 3 years as a result of better recycling practice. The exercise has involved estimation, percentages, measures and money.

NCETM | Measuring racket performance
