AI Thread Summary
An object can achieve flight without aerodynamic shaping or chemical propellant through unconventional means, such as using electric power or other creative methods. A humorous example is the use of a JATO rocket attached to a car, which led to a notable incident involving a 1967 Chevy Impala. The vehicle reached extreme speeds of 250-300 mph before becoming airborne for 1.3 miles, ultimately crashing into a cliff. This incident highlights the potential for non-traditional flight methods, albeit with dangerous consequences. Such discussions illustrate the innovative yet risky nature of achieving flight outside conventional aerodynamics.

The question above and-
How can it achieve flight without chemical propellant?( Electric?)
Are there other ways?
 
Science news on Phys.org
Well, I've got a pickup truck out back I like to stand on top of and throw baseballs down. Achieves flight pretty well after the arm gets warmed up.
 
ifin you got ennuf juice,,you can make her fly!
see 1995 Darwin Award: JATO Rocket

Named in honor of Charles Darwin, the father of evolution, the Darwin Awards commemorate those who improve our gene pool by removing themselves from it.


clown attached war surplus rocket (JATO - Jet Assist Take Off is rocket attached to C130 airplane to help it take off from short run way) to his car and achieved flight ..fir a while..see DarwinAward. com

The facts, as best as could be determined, are as follows:

The operator was driving a 1967 Chevy Impala. He ignited the JATO unit approximately 3.9 miles from the crash site. This was established by the location of a prominently scorched and melted strip of asphalt. The vehicle quickly reached a speed of between 250 and 300 mph and continued at that speed, under full power, for an additional 20-25 seconds. The soon-to-be pilot experienced G-forces usually reserved for dog-fighting F-14 jocks under full afterburners.

The Chevy remained on the straight highway for approximately 2.6 miles (15-20 seconds) before the driver applied the brakes, completely melting them, blowing the tires, and leaving thick rubber marks on the road surface. The vehicle then became airborne for an additional 1.3 miles, impacted the cliff face at a height of 125 feet, and left a blackened crater 3 feet deep in the rock.

Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
After my surgery this year, gas remained in my eye for a while. The light air bubbles appeared to sink to the bottom, and I realized that the brain was processing the information to invert the up/down/left/right image transferred to the retina. I have a question about optics and ophthalmology. Does the inversion of the image transferred to the retina depend on the position of the intraocular focal point of the lens of the eye? For example, in people with farsightedness, the focal point is...
