Pulsars, since their discovery in 1967, have been regarded as natural laboratories for the study of matter under extreme physical conditions of density, gravity and intensity of magnetic fields. In recent years, with a rapidly developing economy, China has made great achievements in the fields of cosmology, astronomy and astrophysics. This economic scenario, combined with China's millennial tradition of seeking to expand the frontiers of knowledge, led to the planning and construction of several large radio telescopes and the launch of a series of deep space exploration satellites. As a concrete result of this broad effort, today China is gradually advancing to the forefront of scientific research and technological innovation in the field of Pulsar Astronomy. The main highlight of this book is to present the Five-hundred-meter Aperture Spherical Telescope (FAST) and its new discoveries and scientific results. To date, FAST has discovered more than 800 new pulsars through its galactic plane survey and drift sweep. The high-precision millisecond pulsars found by FAST can be used to detect extremely lowfrequency gravitational waves, establish pulsar timing patterns, and search for unknown objects in the solar system. For the vast majority of readers, this book undoubtedly represents a rich source of documentation, information and learning about pulsars and their impact on modern astrophysics and particularly about China's contribution to new achievements in this area.

FM Antenna
Style: STR-AN1000 AV Receiver only
The Sony receiver is a good piece of equipment but it lacks an FM antenna to receive channel's in the local area. I understand signal propagation, bandwidth, side lobs and RF dead spots and bit more. I can get a $12 box radio set it up in the same spot and the reception is great. nuff said

Return window closed 7 days before the unit failed and will not output video signal to OLED tv.
Style: STR-AN1000 AV Receiver only
Avoid buying renewed. Learned my lesson so far. Unit stopped putting out video signal 7 days after return window closed. Now I am stuck with a very clunky and expensive audio box.

real time and energy saver, as well as $
Size: 16AWG Wiring Harness-2 Leads
If you have a set of LED lights that didn't come with a harness , you can't beat this for the price. By the time you figure in the cost of the parts ( wire, switch, crimps/connectors, not to mention a relay if you are using one) to hardwire a set of lights, let alone the time to assemble, this set up is cheaper by far. harness length is ample, you get a pair of pigtails with connectors for a pair of lights, the relay, switch, fuse block and fuse, and ring terminals for power all assembled for what a switch and some wire would cost. Made everything quick, cheap, and easy.

Great wiring harness for light installations.
Size: 16AWG Wiring Harness-2 Leads, Size: 16AWG Wiring Harness-2 Leads
This is a great wiring harness for LED lights. These come in one or two leads application. All that means is that they come ready for one or two lights, depending on your installation. The plug in connectors for each light comes with the set so that is a plus. I’ve attached a picture of the plug/connector for the lights so you can take a look at them. Although the relay is an “overkill” for low wattage LEDs, it’s OK to have it just in case you decide to change your lights for larger ones or halogens, in the future. In my case I will be using this harness in my motorcycle. It is very long for my need, which is great for cars, but too long for motorcycles since you have to remember that room/space is scarce in motorcycles. I ended up cutting the wires to my desired length and using heat shrink butt connectors and “glued” heat shrink covers for waterproofing the connection points. All in all these are great quality and I am very happy with them.
