Each year it seems another technical topic is celebrated
Chemistry, crystallography, statistics,… 2015 it is LIGHT.
We bring the topic up in our professional development
class and learn things along the way.
An innovative idea of light sheets used in microscopy of
biological samples is highlighted.
While a hundred pages are still to be digested, it is
important to bring up conflicts that occur, how
they are represented and their outcomes in a must
read book called Merchants of Doubt.
2015 YEAR OF LIGHT AND LIGHT TECHNOLOGIES
SOURCE: IYOL Blog
The scientific sponsors include European Physical Society,
SPIE, Optical society, IEEE Photonics Society, American
Physical Society and international light sources network.
Many of the discoveries concerning coherent and incoherent
light will enjoy commemorations and the celebration will be
an educational opportunity.
LIGHT SHEET MICROSCOPE
SOURCE O. Hanrahan, Photonics, July/August 2014, p. 20
Light Sheet Microscopy LSM advances biological studies
The author compares and contrasts LSM with confocal
microscopy with lower phototoxicity and higher speed.
Scattering and absorption are larger issues.
LSM can optically section samples, be minimally invasive
by using two objective lenses (focus the light sheet
and collect fluorescence emission), a digital camera
and 3-D image display. Speed, sample handling and
cost of total system will lower with time as this
method will find its place.
MERCHANTS OF DOUBT

Doubt,” Bloomsbury Press NY, 2010
“How a handful of scientists obscured the truth on
issues from tobacco smoke to global warming.”
This is scintillating reading describes how a small
group of prominent individuals create smokescreens
to block and obfuscate issues which have impact
on commercial and big businesses. I read just this morning
an op-ed piece about how EPA rules should not be allowed
because it will raise costs. As we realize, this can, properly
communicated and used, motivate innovation.
The book documents the 50+ year history of conflicts
of business interests with scientific results and conclusions–
from tobacco-cancer, second-hand smoke-illnesses,
pesticides-Silent spring, acid rain-acidification of
waterways, coal burning-air pollution, global warming-
The “debates” were manufactured, the authors claim, based
on PR misdirection and ‘alternate reality’ views. Interesting
commentary by one of the sources to escape the public
attention to previous public positions. These approaches
are legalistic possibilities, and in legal terms, do not have to
be true, but only plausible.
