We’ve seen a sharp evolution in designs from Amazon. The most primitive was this testing drone we saw from them back in 2013:
To me, this is the most exciting design because it is both a sharp departure from what came before, yet still integrates elements of each previous iteration, showing that the designers/engineers are learning. The total number of rotors has again been changed, this time to 6, and the rear propeller has been nixed. The dual fixed wings have been replaced by a single wraparound wing that takes a hexagonal configuration. The drone takes off vertically, like a helicopter, but then pitches forward at an angle for straight-line flight, using the lift provided by the unusual wing design.
The IETF community will (I hope) continue to document and explore such principles, informed by shared values. RFC8890 makes a small contribution to this, by asking the IETF community to favor end users of the Internet — in other words, actual people — over other stakeholders that ask for their needs to be met, when there’s a conflict.
We believe the Celera 500L is the biggest thing to happen to both the aviation and travel industries in 50 years. The Celera 500L has a maximum cruising speed of at least 700km per hour and a range of over 7000km. It also has impressive fuel economy, achieving 7 km / liter and 11 km / liter. A traditional business jet with similar capabilities to the Celera 500L, including its 6-passenger capacity, typically achieve 0.5 km / liter, making Otto’s design dramatically more economical, as well as more environmentally friendly. The Celera 500L will have an unbelievably low per-hour flight cost of just $328.
Can vaccines for wildlife prevent human pandemics?
the concept of self-disseminating vaccines to prevent spillovers “is definitely intriguing.” The effort could also help to highlight the interconnection between the health of humans, animals, plants and the environment as a whole. “We have to stop being reactive and trying to stop something in the middle of the crisis”
This demonstrates that universal computation is well within the reach of molecular biology. It is therefore reasonable to assume that life has evolved – or possibly began with – a universal computer that yet remains to be discovered.
A clay tablet inscribed with one of the first known proper names in history sold at auction. It dates to 5.1 ka BP. and is engraved in the archaic Sumerian pictographic script dubbed Uruk III. The topic of this administrative record is beer production.
