Soyuz versus Hwasong 14 Exhaust Plume

July 30, 2017 Mbeljac 0

This is cool. Just some nerd fun. Check out the first video. This shows a launch of the Russian Soyuz space launch vehicle, the old workhorse of the Soviet and Russian space programme. It’s lineage goes all the way back to the R7 Semyorka, the first Soviet ICBM and the […]

Some Implications of North Korea’s July 28 Hwasong-14 ICBM Test

July 30, 2017 Mbeljac 0

On July 28 North Korea test launched the Hwasong-14 (KN-20) ICBM, at about the time Pyongyang marks “victory” in the Korean War. According to the North Koreans the second test launch of the Hwasong-14 was brought forward. Reliability is essential for nuclear deterrence, and a credible long range missile developed […]

North Korea’s Second ICBM Test: Preliminary Analysis

July 29, 2017 Mbeljac 0

A very quick and preliminary first thoughts post on North Korea’s second ICBM test, which came upon the date that North Korea celebrates “victory” in the Korean War. These thoughts are very much subject to further information, currently limited, and release of imagery and videos of the test by North […]

Iran’s Simorgh Rocket Test and the JCPOA

July 28, 2017 Mbeljac 0

By now I am sure we have seen coverage of Iran’s flight test of the Simorgh Space launch Vehicle. Initial reports suggested that Iran launched a satellite into Earth orbit, but that was most certainly not the case. The Simorgh flight test was reportedly successful although some reports I’ve seen, […]

Can a Nucleus Have Four Neutrons and Two Faces?

July 25, 2017 Mbeljac 0

Two cool new results in nuclear physics that promise to extend our understanding of the nucleus have been in the news. The first relates to the possibility of a stable four neutron nucleus, and the second on the relative stability of some light nuclei with deformed shapes occasioned by energy […]

The Signal and the Noise: Revolutionary New Cosmology at LIGO?

July 23, 2017 Mbeljac 0

The discovery of gravitational waves promised to usher in a new age of empirical cosmology, with potentially significant implications for our theoretical understanding of the physical world. Roger Penrose in a new paper is claiming that this promise has been delivered. At issue is “noise” in the signal of gravitational […]

The Ecology of Nuclear War

July 22, 2017 Mbeljac 0

A recent study of the ecological consequences of a limited nuclear exchange involving the established nuclear weapon states concludes that it would take a relatively small number of nuclear detonations to trigger significant climatic impacts, and that upon a planetary scale. Essentially, the study, by Liska, White, Holey and Oglesby, […]

Biodiversity Loss and Biological Annihilation

July 18, 2017 Mbeljac 0

Recently I happened to come across a book on biodiversity loss which stated, in the introduction, that much had been written about the crisis of biodiversity loss but little about what may be done about it. That book was written in 1975. Matters, of course, are much worse now and […]

Additional Reprocessing of Plutonium at Yongbyon?

July 16, 2017 Mbeljac 0

A study of the thermal patterns at the Yongbyon Nuclear Scientific Research Centre conducted and published by researchers at 38North suggests that North Korea has engaged in two plutonium reprocessing campaigns not previously, publicly, known which naturally boosts external estimates of the available plutonium stock that North Korea has for […]
