# behav: backward walking, navigational uncertainties (among Cataglyphis velox)

<< Current opinion in insect navigation assumes that animals need to align with the goal direction to recognise familiar views and approach it. Yet, ants sometimes drag heavy food items backward to the nest and it is still unclear to what extent they rely on visual memories while doing so. >>

<< ants do indeed recognise and use the learnt visual scenery to guide their path while walking backward. In addition, the results show that backward homing ants estimate their directional certainty by combining visual familiarity with other cues such as their path integrator and the time spent backward. >>

# life: a case of extreme swing (3): he's impeachable/ impeached, or (maybe) not

<< Now that the House of Representatives has voted to impeach President Donald Trump, what is the constitutional status of the two articles of impeachment? Must they be transmitted to the Senate to trigger a trial, or could they be held back by the House until the Senate decides what the trial will look like, as Speaker Nancy Pelosi has hinted?  The Constitution doesn’t say how fast the articles must go to the Senate. Some modest delay is not inconsistent with the Constitution, or how both chambers usually work. >>

<< Strictly speaking, "impeachment" occurred – and occurs - when the articles of impeachment are presented to the Senate for trial. And at that point, the Senate is obliged by the Constitution to hold a trial. >>

# gst: the complex dynamics of a transition

<< The transition state is a central concept of chemistry (..) Everything we think about in reactions really hinges on the structure of the transition state, which we cannot directly observe. >> Robert Field.

<< there are two different mechanisms competing for transition states, >>

# life: oops! trust in (British) politics

<< In previous British elections, to say that trust was the main issue would have meant simply that trust is the trump card – whichever leader or party could secure most trust would win. Now, the emerging question about trust is whether it even matters anymore. >>

<< Even many Labour voters don’t rate their leader as trustworthy. Neil Hall/EPA >>

<< These are moral judgements of the utmost significance. So it suggests that British democracy is in some moral jeopardy, when the leaders of the two major parties, the only likely candidates for the premiership, were rated so low on trustworthiness by the public, including supporters of their own party. For example, according to one YouGov poll, 53% of respondents thought Johnson untrustworthy, while for Corbyn the figure was 57%. (..) These figures suggest not only seriously depleted trust but also a substantial readiness amongst voters to separate trustworthiness from electability.  (..) A lack of trustable people creates insecurity, and in this anxious environment some people will want to convince themselves, whatever the evidence, that they have found a trustworthy leader.  (..) On that front, the most significant outcome may not be the seats won by the competing parties, but the national profile as expressed in the popular vote, and what it tells us about whether trust matters. >>
