Transgender, transhuman: technological advances offer increased choices …

Posted: January 23, 2023 at 5:49 pm

In the 2019 TV series Years and Years, a young girl dissatisfied with her life reveals to her parents she is trans. Her parents readily express their acceptance and support for their daughters supposed desire to have a sex change. But then she tells them she is not transgender but transhuman, and wishes to leave her physical body behind to become data. Her parents are shocked and then furious.

As this scene shows, although technological advances may offer new ways for people to lead their lives, they can also create new prejudices. A growing awareness of trans issues both transgender and transhuman is stimulating general debate. But we should not assume that discussion of bodily changes necessarily means progression towards a more equal society.

The human body comes in a huge variety of shapes, sizes and colours, yet people outside the perceived norm have often been seen as threatening, ridiculous or hateful. For example, the Hijra, an Indian transgender community dating back 4,000 years, may have achieved legal recognition in 2014 but faces renewed discrimination today.

The possibilities for physical change have never been greater. From tattoos to cosmetic surgery, gender reassignment procedures to bionic implants, people have an increasing number of ways to alter their appearance and the way they live.

As Years and Years hints at, technological progress doesnt only affect gender identity. While prosthetics and implants for medical purposes have been around for years, a whole new range of elective body augmentations are becoming possible. The term transhumanism describes the evolution of the human race beyond its current state, particularly through the implantation of technology in the body.

This bio-hacking blurs the line between human and non-human. For example, Professor Kevin Warwick, often referred to as Captain Cyborg, had a microchip implanted that enabled him to control the lights and doors in his lab. He then had further surgery to connect an electrode array with his nervous system, which allowed him to control a robotic arm with his mind.

While transgender people have been around for thousands of years, they are offered new possibilities through technology. In contrast, transhumanism is only possible because of technology. In either case, the increase in body modification and gender reassignment procedures suggests now is a good time to reconsider our notions of gender and identity more generally, especially as we live in such an interconnected world. The ability to decide how our body appears and performs in society is transferring more power to the individual, and diverse lifestyle choices are proliferating.

But the increase in alternative ways of living also gives rise to more and different types of discrimination. There has been a sharp rise in transgender hate crimes in the UK, and even an alleged assault in France linked to transhuman discrimination. In this case, staff members in a fast-food restaurant tried to forcibly remove a mans augmented reality headset, as they thought he was filming them, but it was attached to his skull.

Fiction, in literature, film and TV, plays an important role in showing alternative ways of living. Such stories reflect and foster an awareness and experience of current issues in society. So it is not surprising that a variety of fictional transhuman and transgender protagonists have emerged over recent years. They also can help us to anticipate possible avenues of discrimination.

Two very recent examples of transgender and transhuman matters in British fiction are Jeanette Wintersons latest book, Frankissstein, and the previously mentioned series Years and Years, created by Russell T Davies. Both of these works depict alternative modes of gender and identity in an increasingly tech-dominated world, showing how technological advances can offer increased choices for people but also create new prejudices.

In Franskissstein, the human body is subjected to radical changes in a contemporary world of cutting-edge technology and artificial intelligence (AI). The characters, including a transgender doctor, a Welsh sex-bot entrepreneur and an AI professor, collectively push at the boundaries of what it means to be human. Gender reassignment, sexual relations with robots, and the transfer of the mind to digital form are all depicted. Each of these new ways of living are met with resistance and intolerance by others in the book.

Meanwhile, in Years and Years, the character Daniels status as a gay man is unquestioningly accepted by his family and friends. By contrast, the desire of his niece, Bethany, to become transhuman through tech implants and bio-hacking is met with anger, fear, and revulsion. 30 years on from the groundbreaking, and at the time shocking to many, presentation of a gay relationship on Eastenders, the portrayal of Daniel shows how far the acceptance of same-sex relationships on TV has come. This also suggests that the desire to become transhuman may take many years to become more widely tolerated.

In real life, as in fiction, the expanding range of lifestyle choices available now and in the future will not simply lead to increased tolerance of difference. Although transgender and transhuman issues are becoming increasingly visible, new forms of discrimination will arise as people move further away from traditional modes of living.

But if the end-goal of transhumanism is to leave our biological origins entirely behind us, then a posthuman world would also be a postgender world. In which case, so much of the discrimination that focuses on the body would become extinct.

Transhuman – TV Tropes

"Your mind is software. Program it. Your body is a shell. Change it. Death is a disease. Cure it. Extinction is approaching. Fight it."

Transhumans are people who have been artificially enhanced with mental and/or physical abilities beyond what is considered normal for the species from an evolutionary standpoint. Despite the name, species-wide artificial improvement is not actually limited to humans other species or entities that are enhanced count as well. The means used for this augmentation can be anything from magic to science.

Transhumanism as a movement and a philosophy implies that people can, and should, become transhuman en masse rather than be restricted to a select few who came across such abilities through extraordinary circumstances. By implying that scientific progress may grant superhuman powers to anyone with appropriate knowledge and resources, and without any regard for predestination, luck or hard work, transhumanism is notoriously opposed to narrative exceptionalism. A positive portrayal of transhumanism generally places a work on the Enlightenment side of the Romanticism Versus Enlightenment spectrum while a negative portrayal or conspicuous absence of it does the opposite.

Proponents argue that transhumanism is an essential part of our future lives, because...

The opponents also have many arguments to support their views.

Historically, media has not been kind to transhumanists. For a long time, desiring for human improvement has been the province of dictatorial dystopian societies or a Mad Scientist with a God complex. Anarcho-Cyber Punk writers focused on how cybernetic augmentation could be abused to the detriment of society, as well as how it eats people's souls. Religious Moral Guardians object to the idea on the ground of tampering with God's creation (though, ironically, many religions espouse a transhuman plane of existence free from the sinfulness of flesh). And, particularly with the rise of far right and Neo-Nazi movements in recent years, there is the concern that transhumanism can serve as a rebranding of the old Eugenics Movement designed to make it seem more palatable. In fiction, upgrading a human being through science was usually portrayed as a bad idea strictly due to the Squick factor, and even when it wasn't, it was either shown as a Deadly Upgrade with significant disadvantages or a part of an Utopia Justifies the Means plan objectionable on moral grounds.

Curiously enough, as augmentation-based medical therapies gain traction through both in-vivo genetic engineering and advanced prosthetics and improve human lives in ways thought impossible in the past, the criticism has gradually subsided. Today, many would agree that, from a strictly utilitarian standpoint, transhumanism has a great potential to be used for good, with the criticism being mainly aimed towards the implementation and its potential pitfalls and dangers rather than the idea itself.

The word "transhuman" is now found in legitimate scientific and political debates.

For some of the abilities a Transhuman might have, see the Stock Superpowers Index; related to How to Give a Character Superpowers. See also No Transhumanism Allowed. This may be used as an aspect of a Cyberpunk or Post-Cyberpunk setting.

Compare the bermensch,notemeaning "over-man" or "superman" in German whose transcendency is psychological and moral in nature rather than physical.

Sub-Trope of Trans Nature. Mutants and Human Subspecies may or may not be a result of this, and they may be crippled instead of "enhanced". Contrast Formerly Sapient Species. Not to be confused with Transgender people, though medically transitioning is a mild form of real life transhumanist modification.

How to Play Blackjack: Your Ultimate Guide for 2022

Posted: at 5:44 pm

Some blackjack tables have a practice of discarding the first card from each new shoe before beginning play. Rules about seeing this card vary from place to place, sometimes even from dealer to dealer.

Some show it to the table automatically, some have to be asked, and (rarely) some casinos have a policy of never showing it to the player.

Card counters would, of course, prefer to see the burn card, but generally dont regard it as a big deal if they cant, as there are usually some quantity of cards behind the cut card that they will never get to see anyway.

This practice actually wasnt designed to deter card counting. It was actually designed to prevent an unethical trick called card steering.

It prevents players (or shady dealers) from marking the top card, or from accidental exposure to players prior to the deal. If the casino wants to burn cards to deter card counting, they would periodically burn several cards in the middle of the shoe to more effectively mess with player counts.

The goal of Blackjack is to have a hand that totals higher than the dealers, but doesnt total to higher than 21. If your hand totals higher than 21, it is called a bust, which means you are out of the game. The game starts with everyone besides the dealer placing a bet. Then, the dealer deals 1 card face up to each player and 1 card face up to themselves. Everyone is dealt one more face-up card besides the dealer, whose second card is dealt face down. Cards 2 through 10 are scored using their face value, and Jacks, Queens, and Kings are all equal to 10. Aces can be either 1 or 10, and you can choose their value throughout the round if you have one. If your two face-up cards total 21, you automatically win one and a half times your bet from the dealer, and youre done for that round. Otherwise, the dealer asks whether you want another card from the top of the deck. If you do, say hit or motion toward yourself with your hand. Theres no limit to how many cards you can ask for, but once your hand totals higher than 21, you bust and the dealer gets your bet. If you dont want any more cards, say stay or wave your hand over the table. Once the dealer has gone around the table, they flip up their face-down card. If its 16 or under, they have to take another card. If its 17 or higher, they have to stay with their hand. If the dealer busts, every player thats still in that round wins twice their bet. However, if the dealer doesnt bust, only the players whose hands are higher than the dealers win twice their bet. Everyone else loses their initial bet. Once the round is over, all of the players place a new bet, and another round begins. If you want to learn strategies to win blackjack or proper casino etiquette while playing, keep reading!

New NASA Nuclear Rocket Plan Aims to Get to Mars in Just 45 Days

Posted: at 5:38 pm

We live in an era of renewed space exploration, where multiple agencies are planning to send astronauts to the Moon in the coming years. This will be followed in the next decade with crewed missions to Mars by NASA and China, who may be joined by other nations before long.

These and other missions that will take astronauts beyond Low Earth Orbit (LEO) and the Earth-Moon system require new technologies, ranging from life support and radiation shielding to power and propulsion.

And when it comes to the latter, Nuclear Thermal and Nuclear Electric Propulsion (NTP/NEP) is a top contender!

NASA and the Soviet space program spent decades researching nuclear propulsion during the Space Race.

A few years ago, NASA reignited its nuclear program for the purpose of developing bimodal nuclear propulsion a two-part system consisting of an NTP and NEP element that could enable transits to Mars in 100 days.

As part of the NASA Innovative Advanced Concepts (NIAC) program for 2023, NASA selected a nuclear concept for Phase I development. This new class of bimodal nuclear propulsion system uses a "wave rotor topping cycle" and could reduce transit times to Mars to just 45 days.

The proposal, titled "Bimodal NTP/NEP with a Wave Rotor Topping Cycle," was put forward by Prof. Ryan Gosse, the Hypersonics Program Area Lead at the University of Florida and a member of the Florida Applied Research in Engineering (FLARE) team.

Gosse's proposal is one of 14 selected by the NAIC this year for Phase I development, which includes a US$12,500 grant to assist in maturing the technology and methods involved. Other proposals included innovative sensors, instruments, manufacturing techniques, power systems, and more.

Nuclear propulsion essentially comes down to two concepts, both of which rely on technologies that have been thoroughly tested and validated.

For Nuclear-Thermal Propulsion (NTP), the cycle consists of a nuclear reactor heating liquid hydrogen (LH2) propellant, turning it into ionized hydrogen gas (plasma) that is then channeled through nozzles to generate thrust.

Several attempts have been made to build a test this propulsion system, including Project Rover, a collaborative effort between the US Air Force and the Atomic Energy Commission (AEC) that launched in 1955.

In 1959, NASA took over from the USAF, and the program entered a new phase dedicated to spaceflight applications. This eventually led to the Nuclear Engine for Rocket Vehicle Application (NERVA), a solid-core nuclear reactor that was successfully tested.

With the closing of the Apollo Era in 1973, the program's funding was drastically reduced, leading to its cancellation before any flight tests could be conducted. Meanwhile, the Soviets developed their own NTP concept (RD-0410) between 1965 and 1980 and conducted a single ground test before the program's cancellation.

Nuclear-Electric Propulsion (NEP), on the other hand, relies on a nuclear reactor to provide electricity to a Hall-Effect thruster (ion engine), which generates an electromagnetic field that ionizes and accelerates an inert gas (like xenon) to create thrust. Attempts to develop this technology include NASA's Nuclear Systems Initiative (NSI) Project Prometheus (2003 to 2005).

Both systems have considerable advantages over conventional chemical propulsion, including a higher specific impulse (Isp) rating, fuel efficiency, and virtually unlimited energy density.

While NEP concepts are distinguished for providing more than 10,000 seconds of Isp, meaning they can maintain thrust for close to three hours, the thrust level is quite low compared to conventional rockets and NTP.

The need for an electric power source, says Gosse, also raises the issue of heat rejection in space where thermal energy conversion is 30-40 percent under ideal circumstances.

And while NTP NERVA designs are the preferred method for crewed missions to Mars and beyond, this method also has issues providing adequate initial and final mass fractions for high delta-v missions.

This is why proposals that include both propulsion methods (bimodal) are favored, as they would combine the advantages of both. Gosse's proposal calls for a bimodal design based on a solid core NERVA reactor that would provide a specific impulse (Isp) of 900 seconds, twice the current performance of chemical rockets.

Gosse proposed cycle also includes a pressure wave supercharger or Wave Rotor (WR) a technology used in internal combustion engines that harnesses the pressure waves produced by reactions to compress intake air.

When paired with an NTP engine, the WR would use pressure created by the reactor's heating of the LH2 fuel to compress the reaction mass further. As Gosse promises, this will deliver thrust levels comparable to that of a NERVA-class NTP concept but with an Isp of 1400-2000 seconds. When paired with a NEP cycle, said Gosse, thrust levels are enhanced even further:

"Coupled with an NEP cycle, the duty cycle Isp can further be increased (1,800-4,000 seconds) with minimal addition of dry mass. This bimodal design enables the fast transit for manned missions (45 days to Mars) and revolutionizes the deep space exploration of our Solar System."

Based on conventional propulsion technology, a crewed mission to Mars could last up to three years. These missions would launch every 26 months when Earth and Mars are at their closest (aka. a Mars opposition) and would spend a minimum of six to nine months in transit.

A transit of 45 days (six and a half weeks) would reduce the overall mission time to months instead of years. This would significantly reduce the major risks associated with missions to Mars, including radiation exposure, the time spent in microgravity, and related health concerns.

In addition to propulsion, there are proposals for new reactor designs that would provide a steady power supply for long-duration surface missions where solar and wind power are not always available.

Examples include NASA's Kilopower Reactor Using Sterling Technology (KRUSTY) and the hybrid fission/fusion reactor selected for Phase I development by NASA's NAIC 2023 selection.

These and other nuclear applications could someday enable crewed missions to Mars and other locations in deep space, perhaps sooner than we think!
