Category: W 3: Modeling Electromagnetic Radiation (HS)

Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other.​

The physics of pollinator attraction

GwynneL.

The physics of pollinator attraction SUMMARY: This article focuses on the physical properties of plants that have evolved to help them select the appropriate pollinators and discourage non-pollinators (nectar stealers). The first feature the article addresses is the shape of the cells. Flower petals often have cone-shaped cells to help scatter more light. This gives… Continue reading The physics of pollinator attraction

Electronic Tongues

GwynneL.

A Versatile Electronic Tongue Based on Surface Plasmon Resonance Imaging and Cross-Reactive Sensor Arrays-A Mini-Review SUMMARY: Scientists are trying to create electronic tongues (eT) and noses (eN) that act like human tongues and noses. These artificial sensors are different from traditional sensors in that they don’t recognize individual molecules, but heterogeneous liquids and gases. In… Continue reading Electronic Tongues

Exposure to Radiofrequency Electromagnetic Fields From Wi-Fi

GwynneL.

 Exposure to Radiofrequency Electromagnetic Fields From Wi-Fi in Australian Schools SUMMARY: People are often worried about children being exposed to WiFi radiofrequency electromagnetic fields in the classroom, especially when many children are simultaneously downloading or uploading something on their laptops. This study went to 23 different schools in Australia and measured the strength of the… Continue reading Exposure to Radiofrequency Electromagnetic Fields From Wi-Fi

Biological effects and mechanisms of shortwave radiation

GwynneL.

Biological effects and mechanisms of shortwave radiation SUMMARY: This article review looked at the research that has been completed on the effects of shortwave radiation on the biological system. It’s been shown that shortwave electromagnetic field (SW-EMF) was successful at slowing down the growth of certain cancer cells, promote healing in skin, help with pain… Continue reading Biological effects and mechanisms of shortwave radiation

Beaming Simulated Space Ice

GwynneL.

Enantiomeric separation of complex organic molecules produced from irradiation of interstellar/circumstellar ice analogs(NOT OPEN ACCESS) SUMMARY: To simulate conditions in space and in asteroids and meteorites, scientists put simple gases (water, carbon dioxide, ammonia, and methanol) into a low temperature and low pressure chamber. Then, using UV light, they irradiated these gases (which at the… Continue reading Beaming Simulated Space Ice
