Uma manhã de frio no Vermont. Fica registado que ainda fizemos uma pista antes de recolher ao bar.

Tired minds

Why is it that when we think too hard for too long, our minds become tired? We still think, but our thoughts become dazed and confused, as if logic were unnatural and required effort. Why are logic and creativity efforts for our brain? What does our brain do when it is tired?

Religion...

... is the land where all your dreams are possible.

If there is even a iota of a chance that they are possible, try it.

Snails = snow mails.

"Because of the impending snowstorm, we have decided to postpone Connie Cepko’s seminar for this afternoon. Please distribute this information to your departments. Thanks and enjoy the snow!"

"Due to the inclement weather we recommend that if it is possible for you to go home that you do try to go before the weather further deteriorates. The administrative (admin, lab ops, and finance) staff will be leaving in the next few hours."

"Apparently there has been some anxiety about the fact that the admin staff left early. Don't worry, they filled the beer fridge before they left."

Really cool science

"Understanding the “ecology of cholera,” noted Colwell, requires understanding the factors in their biocomplexity: global weather patterns, aquatic reservoirs like marine bays and estuaries, zooplankton and their surface-attached cells, biofilms, and the deep sea itself, the ancient home of Vibrio cholerae.

Environment aside, cholera could be prevented (as it is in the West) by the simple expedient of making clean water universally available. This will not happen easily or soon, said Colwell. To bridge the gap, her team came up with a low-tech answer in 1998 in Bangladesh: straining drinking water through sari cloth folded over at least four times. The native fabric creates a 20 micron-size filter, which strains out the zooplankton associated with cholera.

A pilot study in one Bangladesh village showed that this simple step reduced cholera cases by 50 percent in the fall of 2000."

Hoje, na piscina, uma mulher de fato banho comprido (ate' ao joelho e ate' aos cotovelos) e um veu. Um veu! Na piscina.

'A saida eu e um amigo convidamo-la para o jacuzzi.

It's Spring! Sprrriing!

Oh what a feeling, tchanananaaaa!

Uma aragem

-12°C, Feels Like -23°C

Uma pontinha de frio para despedida do inverno. A partir do final da semana, a temperatura vai estar sempre acima de 0, ou seja, adeux o' gelo.

Coisas da idade

Dexei de ter qualquer paciencia para miudas convencidas, por muito giras que sejam. Agora vou sair para estar com amigos, e pela musica. E' bom!!! Mais inesperado, e' que cada vez gosto mais de musica , electro-funk, house e soul. Boa musica e' um trip incomparavel. Sera' que aos 40 ainda vou estar aos saltos com um bom dj?

Condoms

In Europe, condoms are sold in packages of 12.
In the US, they are sold in packages of 3.

Cunning marketing, or physiological adaptation?

Medicos Reinventam o Integral!!!!!!!!

Em certos livros de medicina o integral de uma funcao e' chamado de ... AUC = Area Under the Curve.

fico sem palavras. Mas ha' mais... oh sim, se ha' mais.
Na sua santa ignorancia, estes medicos decidiram que afinal era preciso calcular a dita AUC porque "maior" ou "menor" ja nao chega para as exigencias da ciencia de hoje. Entao entra em cena um tal de Tai, que propoe... wait for it... the Tai Method of computing the AUC!!!!! O resto, so' visto:

"A mathematical model for the determination of total area under glucose tolerance and other metabolic curves

MM Tai
Obesity Research Center, St. Luke's-Roosevelt Hospital Center, New York, New York.

OBJECTIVE--To develop a mathematical model for the determination of total areas under curves from various metabolic studies. RESEARCH DESIGN AND METHODS--In Tai's Model, the total area under a curve is computed by dividing the area under the curve between two designated values on the X-axis (abscissas) into small segments (rectangles and triangles) whose areas can be accurately calculated from their respective geometrical formulas. The total sum of these individual areas thus represents the total area under the curve. Validity of the model is established by comparing total areas obtained from this model to these same areas obtained from graphic method (less than +/- 0.4%). Other formulas widely applied by researchers under- or overestimated total area under a metabolic curve by a great margin. RESULTS--Tai's model proves to be able to 1) determine total area under a curve with precision; 2) calculate area with varied shapes that may or may not intercept on one or both X/Y axes; 3) estimate total area under a curve plotted against varied time intervals (abscissas), whereas other formulas only allow the same time interval; and 4) compare total areas of metabolic curves produced by different studies. CONCLUSIONS--The Tai model allows flexibility in experimental conditions, which means, in the case of the glucose-response curve, samples can be taken with differing time intervals and total area under the curve can still be determined with precision.

Bravo Tai!!! e' ja' um Nobel e uma visita ao tumulo do Leibniz!!!
