Weds January 17, 2018 at 8:00pm, at the Beckman Auditorium at Caltech

Andrei Faraon - "Flat Metasurface Optics"
The E.C. Watson Lecture Series

For hundreds of years, most optical elements like lenses and polarizers have been fabricated using carefully polished pieces of glass or crystals, and assembled in optical systems such as cameras and microscopes.  In this talk, Faraon will discuss how nano-technology enables new ways to make optical components using fabrication processes already developed in the semiconductor industry.  These nano-patterned structures, named optical metasurfaces, allow for extreme miniaturization of optical systems with applications in consumer electronics and medical devices. 

Dr. Andrei Faraon (B.S. Physics, Caltech 2004; Ph.D. Applied Physics, Stanford 2009) is Assistant Professor of Applied Physics at the California Institute of Technology.  His laboratory specializes in developing nanophotonic technologies for devices that operate close to the fundamental limit of light-matter interaction, with applications in imaging, sensing and quantum information processing.  In 2016, Faraon was named the inaugural KNI-Wheatley Scholar in Nanoscience, established by Chuck and Judith Wheatley and the Kavli Nanoscience Institute.

This month our third Wednesday Lectureship program features Dr. Alan Rubin from the the UCLA Meteorite Lab. This is a subject that heavily depends on the use of the microscope, not just the polarizing microscope, but a variety of illumination techniques extending all the way to the electron-microscope. Our speaker has a life-time of experience using every type of instrument in his study of materials collected in space. There will be microscopes set up with samples for inspection. This meeting is not to be missed! Bring friends who have interest in both microscopy and astronomy.

Speaker: Dr. Alan Rubin, Meteorite Lab, UCLA.
Title: Meteorites and Minerals: Constraints from Microscopy and Geochemistry

Abstract: Among the principal tools cosmochemists use to analyze meteorites are optical and scanning electron microscopes. These instruments provide essential petrographic information that are routinely coupled with compositional analyses to decipher the history of meteorite parent bodies – asteroids, the Moon and Mars – and even late-stage processes of dying stars. The myriad processes of mineral formation in meteorites are revealed by assiduous use of microscopy.

This meeting is a reschedule of that originally planned for March. MSSC's Education Officer, Alan deHaas will lead this hands-on class on 3-dimensional micro-crystals, or more commonly called Micro-Mounts. Alan will start with an informative talk on the study of crystals (mineral micro-mounts), following which he will provide practical instruction on how to prepare micro-mounts. If you have one, bring a stereomicroscope and a good adjustable lamp (or an LED flashlight) to the meeting, along with any micro-mounts that you would like to share with the group.

Abstract: The Joy of Mineral Specimens:
Wednesday 21 March 2018 we will hold a meeting devoted to the pleasures of examining Nature's perfection.  Micromounting - the joy of mineral specimens.  Please bring a stereo microscope and a good adjustable lamp (or an LED flashlight).  Alan deHaas, and maybe some of the other members, will bring in boxes of the small mineral specimens.  Much of these are from the Hudson Collection.  For those who do not have a stereo, a good quality flat field magnifier often serves quite well.  While the crystals to be observed are small, they very frequently are found covering large surfaces.  These bigger pieces are trimmed to yield chunks rarely more than 3cm and quite often just a couple of mm.  Although one might attempt to use higher power - to see more - this is often confusing and completely unnecessary.  Most observations can be made at below 30x.

Please know that while a good size hand specimen may be quite desirable, it is in the smaller crystals that the perfection of their growth can most readily be seen.  The illuminator is as important as the scope, or magnifier.  The manipulation of the light source allows for the observation of surface detail, the relationship between crystals, the appreciation of the clarity of the crystals......  Some text material will be available.  I can guarantee that there will be many "oh my", "wow" and "gee" moments.

Note: For this special meeting we will NOT be gathering in the regular projection room, rather in one of the classrooms where we will all have access to a table.  Our host, Joe Wise will show us what room to use once we arrive.

The Pond Life program is undoubtedly one of our best attended and most exciting hands-on meetings! This is the event that you bring in your microscope (if you have one) and a samples of pond water obtained from your neighborhood: basically pond water, ditch water, puddles, fountain water or any other natural water samples. If you don’t have a pond source then just come and enjoy the collections brought in by others. We hope to have water samples from all over southern California. This is a fun, hands-on meeting, and one at which we'll hope to see new and exciting discoveries.

Suggested equipment list: water samples, microscopes, illuminators and pipettes and tools to play with the water samples. (Extra microscopes are always a good thing to bring for guests to use.)

If you have books or publications that identify Pond Life then do bring those along as well.

Here's a video by Tom Jones showing pond water organisms filmed at the Microscopy Society of Southern California, May 2015, Pond Life Meeting in Santa Monica, CA. The specimen is lake water collected from Lake Gregory, in Crestline, CA., with a 20um pore size plankton net. Two different microscopes were used. The Rotifer is probably Synchaeta sp. and is shown in dark field using an Olympus BH-2, 1.67x projection eyepiece, DCD condenser, mag changer set at 2x, and a DPlan 20x objective. The second and third parts of the video show Stentor sp., also in dark field, using an Olympus SZH Research Stereo Microscope, DF Plan 1x objective, ILLD illuminator base set to dark field, SZH-PT phototube with a 1.67x projection eyepiece. Zoom magnification was set at 64x. A Tucsen TrueChrome II camera at 1080p was used for all parts of the video.

This month's lecture will be a presentation on the milkweed leaf miner. There will also be a brief presentation on using a Sony a77 with the microscope. 

Abstract:
Steven Kutcher M.A. is an entomologist, teacher, artist, and consultant who uses his skills in many different areas.   Steven teaches biology at West Los Angeles College and is known as the Hollywood Bug Man.  He has worked with insects in hundreds of feature films, music videos and commercials.  His work with spiders can be seen in e Arachnophobia and Spider Man.  Steven spends some of his time painting (Bug Art) using insects as his brushes, lecturing, and doing private consulting concerned with insect problems.  A microscope is an important tool for any entomologist.  He has had to use his skills quickly resulting in a number of small inventions and discoveries.   A milkweed leaf miner infested his butterfly garden, he used a microscope to discover information about the fly.  A discussion of the life history and control of this 2mm fly (Liriomyza sp.) will be the first part of presentation and the second part of the talk will be his inventions, observations and discoveries working with insects.

Lectureship sub:  Termite gut microbe’s that live nowhere else in the world

Abstract:
Inside the gut of a single termite reside thousands of species of microbe that live nowhere else in the world, and which are wholly dependent on their host for survival. The termite is entirely dependent on them for its survival, for these protozoans have evolved to digest the wood that termites infamously consume. In this presentation, science filmmaker Danielle Parsons will present a case for termites as the good guys, explain some what is known about the complex termite gut microbiome, and describe her collaboration with scientist Jared Leadbetter of CalTech to capture this award-winning footage of otherworldly organisms. She will screen video of the microbes filmed in high-definition, using several types of microscopy, mostly darkfield, including an extraordinary event serendipitously captured under the microscope!  . 

Second half of the meeting: 
Our Educational director, Alan deHaas will be presenting a brief talk on Stereo Microscope.  The information to be covered is best summarized with the word “STEREO”.
