In Helen Cixous’ essay, ‘The Laugh of Medusa’, she urges women to redefine what their body means to them, not just physically but also socially, emotionally and politically. This could happen by re-writing about your body in a way you deem  fit, the expression you identify with and separating it from how your body has been written about by men. The expression could be how you view your body separate from the patriarchal lense.

It is no secret that a woman’s body is subject to critique. While clothing for men is just a tool to cover themselves as per the surrounding environment, clothing for women isa social and political narrative that dictates their life or as we affectionately call it ‘culturally appropriate’.

The clothing style could vary. It could be a woman covered head to toe in a Burqa, it could be a woman who decides to wear sports-wear in a park or it could be jeans and a top. Everything is critically evaluated by men and by women who work towards protecting the male gaze.

The male gaze is a heterosexual way of looking at female bodies that sexualises these bodies into an object. It is a gaze that runs on the self-affirmative notion that the bodies of women, and what they do with it, is directly linked to how they  appear in front of a man.

In a recent incident in Bangalore, India, popular Indian actress Samyuktha Hegde was abused and threatened by senior political leader of the congress party, Kavitha Reddy,  for wearing sports-wear, in Bangalore’s Agara Lake park. She was exercising with her friend.

Kavitha Reddy initially claimed she was in indecent attire and went onto morally police and then later abused the actress and her friend.  A supposedly progressive political leader gets uncomfortable by what women are wearing. It breaks into an argument and a fight where the politician is supported by five to six men. Later on, the police appear to be appeasing the politician instead of the women who were harassed. Although she did apologise, her apology came after her video went viral, and as a protection for her own political reputation.

To look at Samyuktha Hegde’s clothing as a threat is to view her clothing as an act of obscenity therefore bullying her identity and sense of agency and reducing her to sexual object, who, by putting her in public, apparently gives the men present a right to look at her? Nevermind that she was there to workout like everyone else, her actions were confused as to how men look at her. In the video posted by the actress, the politician is surrounded by men who are championing her on. The politician choses to side with the patriarchal figures in shaming these women. Asking to protect from the male gaze is a far stretch but punishing women for the male gaze is where we should draw a line.

What roles does Kavitha Reddy play? She is the guardian of the male gaze. We find her in our mothers, in our grandmothers, in aunties and sometimes our friends. She understands a woman’s body as an object that is there to be looked at by men. She gets angry at women for wearing certain kinds of clothing but she is not angry at men for looking. The agency in this case always belongs to men.

When Cixous asks women to re-define their identity, she urges us to strangle the moral police that comes alive in such instances. It is the moral police that shames women for wearing clothes that don’t flatter their bodies or clothes that do flatter them. She urges us to reflect upon the source of such vigilance. Do we shame other women because we believe in what we are saying or our identity is partially (or  wholly) shaped by the male gaze?

Whether we chose to wear a burqa, or a dress, or variations of the new type clothing produced everyday, the crux of the matter is that it should not worry anyone apart from the one wearing it. The identity of a woman, sexual or otherwise, has to be redefined to be separated from the men and their gaze. We have to draw a line otherwise people in power will continue to abuse their power and preserve patriarchy and male gaze.

Detecting The Ultra-High Energy Cosmic Rays With Smartphones

Smartphones have become the most commonplace objects in our daily lives. The unimaginable power that we hold in our hands is unrealized by most of us and, more importantly, untapped. Its creativity often gets misused but one can only hope that it’s fascinating abilities would be utilized. For example, did you know that the millions of phones around the globe can be connected to form a particle detector? The following article covers the CRAYFIS (Cosmic RAYs Found in Smartphones) phone-based application developed by the physicists from the University of California—Daniel Whiteson, Michael Mulhearn, and their team. CRAYFIS aims to take advantage of the large network of smartphones around the world and detect the cosmic or gamma rays bursts which enter the Earth’s atmosphere almost constantly.

What Are Cosmic Rays?

Cosmic rays are high velocity subatomic particles bombarding the Earth’s upper atmosphere continuously. Cosmic ray bursts have the highest energy compared to all forms of electro-magnetic radiation. When we say ultra-high energy particles (energy more than 1018^eV), we mean two million times more energetic than the ones that can be produced by the particle colliders on Earth.  These rays are thought to be more powerful than typical supernovae and can release trillions of times more energy than the Sun. They are also highly unpredictable as they can enter Earth’s atmosphere from any direction and the bursts can last for any period of time ranging from a few thousand seconds to several minutes.

Despite many theoretical hypotheses, the sources of these ultra-high energy cosmic rays are still a mystery to us even after many decades of their discovery. These rays were initially discovered in the 1960’s by the U.S. military when they were doing background checks for gamma rays after nuclear weapon testing. Cosmologists suggest that these bursts could be the result of super massive stars collapsing - leading to hypernova; or can be retraced to collisions of black holes with other black holes or neutron stars.

How Do We Detect Them?

When the high-energy particles collide with the Earth’s atmosphere, the air and the gas molecules cause them to break apart and create massive showers of relatively low-energy particles. Aurora borealis i.e., the Northern and the Southern lights are the lights that are emitted when these cosmic rays interact with the Earth’s magnetic field. Currently, these particles are hitting the Earth at a rate of about one per square meter per second. The showers get scattered to a radius of one or two kilometers consisting mostly of high-energy photons, electrons, positrons and muons. But the fact that these particles can hit the Earth anytime and anywhere is where the problem arises. Since the Earth has a massive area, it is not possible to place a detector everywhere and catch them at the exact moment.

Detecting such a shower requires a very big telescope, which logically means a network of individual particle detectors distributed over a mile or two-wide radius and connected to each other. The Pierre Auger Observatory in South America is the only such arrangement where 1,600 particle detectors have been scattered on 3,000 square kilometers of land. But the construction cost of the same was about $100 million. Yet, only a few cosmic ray particles could be detected using this arrangement. How do we spread this network around the Earth?

In addition to being cost-effective, such a setup must also be feasible. The Earth’s surface cannot possibly be dotted with particle detectors which cost huge fortunes. This is where smartphones come into the picture.

Detecting The Particles Using Smartphones

Smartphones are the most appropriate devices required to solve the problem. They have planet wide coverage, are affordable by most people and are being actively used by more than 1.5 billion users around the planet. Individually, these devices are low and inefficient; but a considerably dense network of such devices can give us a chance to detect cosmic ray showers belonging to the highest energy range.

Previous research has shown that smartphones have the capability of detecting ionizing radiation. The camera is the most sensitive part of the smartphone and is just the device required to meet our expectations. A CMOS (Complementary Metal Oxide Semiconductor) device is present in the camera- in which silicon photodiode pixels produce electron-hole pairs when struck by visible photons (when photons are detected by the CMOS device, it leaves traces of weakly activated pixels). The incoming rays are also laced with other noises and interference from the surroundings.  Although these devices are made to detect visible light, they still have the capability of detecting higher-energy photons and also low-ionizing particles such as the muons.

To avoid normal light, the CRAYFIS application is to be run during nighttime with the camera facing down. As the phone processor runs the application it collects data from its surroundings using a camera as its detector element. The megapixel images (i.e., the incoming particles) are scanned at a speed of 5 to 15 frames per second, depending on the frame-processing speed of the device. Scientists expect that signals from the cosmic rays would occur rarely, i.e., around one in 500 frames. Also, there is the job of removing background data. An algorithm was created to tune the incoming particle shower by setting a threshold frequency at around 0.1 frames per second. Frames containing pixels above the threshold are stored and passed to the second stage which examines the stored frames, saving only the pixels above a second, lower threshold.

The CRAYFIS app is designed to run when the phone is not being used and when it is connected to a power source. The actual performance would be widely affected by the geometry of the smartphone’s camera and the conditions in which the data is being collected. Further, once the application is installed and is in the operating mode, no participation is required from the user, which is required to achieve wide-scale participation. When a Wifi connection is available the collected data would be uploaded to the central server so that it could be interpreted.

There is much complicated math used to trace back the information collected from the application. The most important parameters for the app are the local density of incoming particles, the detection area of the phone and the particle identification efficiency. These parameters are used to find the mean number of candidates (photons or muons) being detected. Further, the probability that a phone will detect no candidates or the probability that a phone will detect one or more candidates is given by Poisson distribution. The density of the shower is directly proportional to the incident particle energy with a distribution in x and y sensitive to the direction in which the particle came from. An Unbinned Likelihood (it is the probability of obtaining a certain data- in this case the distribution of the cosmic rays including their energy and direction, the obtained data is arranged into bins which are very, very small) analysis is used to determine the incident particle energy and direction. To eliminate background interference, a benchmark requirement has been set that at least 5 phones must detect and register a hit to be considered as a candidate.

It is impossible to express just how mind-blowing this innovation is. As the days pass, Science and Technology around us keep on surprising us and challenge us to rack our brains for more and more unique ways to deal with complex problems. The CRAYFIS app is simply beautiful and it would be a dream-come-true to the scientists if the project works out and we are able to detect these high energy, super intimidating cosmic rays with smartphones from our backyard.
